These days you can buy microwaves without a spinning tray and the food gets as evenly heated as a regular microwave. They’re easier to clean and you can also put larger containers in them compared to a regular one of the same size
We had a locally made one (Dnipro) which had a rotating emitter instead of rotating plate. Made approximately in 1989 I think. So it wasn't supposed to have standing waves. And yet it did. It always singed the food in the same spots.
I’ll never forget my dad bought us a microwave when they had just come out. He was demonstrating how to cook an egg according to the instructions that came with it. He did exactly the time it recommended. He had put a pin hole in it as instructed. The only space to put the microwave oven was a small utility closet with a shelf. So all we could see was my dad back to us he opened the door and then suddenly we heard him gasp. He turned around and we all gasped too. When taking the egg out it had exploded leaving egg dripping from his eye lids and forehead. That image still stayed with me all these years. My dad died a few years ago. He was always wanting to try new stuff like that. Miss you dad 💔

But even then what I said still isn't as accurate because it is a WAVE, which you can see things on the outside being concentrated because of the wave's FORM, it literally is a wave and squiggly line, the only reason you cannot place it in those spots is literally because the microwave oven itself is not big enough.
Not a terrible idea, but this test isn't perfectly representative. When you have more substantial food in the microwave, it actually affects where the standing wave will be. This occurs because dielectric materials (like your food, or really most anything) concentrate the electric fields present in the microwave oven, while also slowing down wave propagation, making the standing wave different. Now, you'd still be at risk of cold spots in your food, which is where the rotation comes in.
Unfortunately although interesting this isn’t correct. Microwaves have a small wavelength of about a millimetre. The nodes would only be a millimetre apart. This is probably constructive and destructive interference. This is where the waves interfere in some spots constructively so are stronger and destructively in some spots making it weaker. So it’s Not a standing wave. They describe this in the clip but the wavelength given would be closer to radio waves. I can’t test this though because I live in the uk where our cheese isn’t made of plastic.
@@DreadEnder I beg to differ, the wavelength of microwave ovens here in the States is around 12 -13 cm , nodes and anti-nodes would be 1/4 of that figure. Interference phenomena would be the same. And i would pit some American cloth-bound Cabot Cheddar against your finest Wendsleydale. Hmph! "Plastic Cheese" indeed! From the Society that invented Marmite.....!!!!
@@BjarneLinetsky interference is based on wavelength but you can get a large interference region with a relatively small wavelength. It’s strange the wavelength is so long for yours. The whole reason they have a metal grid is to stop them escaping because the largest hole in the grid is a bit smaller than the wavelength. So it’s strange the wavelength would be so large since most here in Europe are about 1,000,000nm (1mm)
This is also why a lot of microwave instructions say to let your food stand for a few minutes before eating it. Partially to prevent you from burning yourself, but also so the hot areas in your food can more evenly distribute into colder areas.
That makes no sense. There is still a present wave form. The point of this video is that no matter where you put your damn food in the microwave, it will be heated unevenly. How do you not see that?
If you do something like chicken nuggets or anything with multiple pieces, the ones on the edge of the plate get hot faster than the ones in the center. Next time I'll try putting the whole plate all the way to one side and see if that helps.
Always put the food on the side of the spinning tray, not the middle. It helps heating your food more evenly. Or if the consistency or size of the food allows it, lay it out in a doughnut shape.
@@lizzalkula376 that's odd. It definitely works for me with the spinning tray ones. The ones without you need to mix the food more often I've found (we have one of those at work). I do mostly heat up frozen veggies with the microwave to retain their nutrients, but so far it has also worked for me when heating up leftovers.
microwaving to retain nutes - something new, it is short wave radiation that boils water inside. everything above 50-60 C destroy ANY vitamins and nutrients that are vital to be eaten raw. when they are frozen ice particles penetrate cells and destroy them as well. you eat fiber - that is it@@CarinaCoffee
....and hopefully a clearer picture of our minds after eating it. Try avoiding microwave anything for a while as you improve your diet, then use it to see if you can feel the difference, and you will - yuck!
@@stevenroper3577 The difference should be minimal if you are mainly microwaving foods that have already been precooked. If they are raw materials that is another thing though - microwaves basically just heat the water inside the food turning them into a self contained pressure cooker, but also drying them out which makes them less palatable.
@@stevenroper3577 before worrying about microwave, americans should be worried about calling that processed sh1t "Cheese", that is much more concerning in my opinion than the microwave, but agree with that too.
I'm a telecommunication engineer, have studied electromagnetic and microwave, and this woman has made better job in a 60 seconds video explaining it than the countless hours I spent with my profs and colleagues!!!
Here is a *simple* explanation of microwaves: The appliance works by emitting microwaves, which are a type of electromagnetic radiation. These microwaves are absorbed by water molecules in food, causing them to vibrate and generate heat through friction. This heat then cooks or reheats the food. The microwave's metal walls reflect the microwaves, ensuring they mainly target the food rather than escaping into the surroundings. See? Simple, right? 😮
@@Patrick-vv3ig not exactly, but the depth of the understanding remained on the surface, videos like these takes it to the deep level of understanding/visualisation so you can have it right inside your mind, at the end, these concepts should become the base blocks of something more complex
For anyone interested, the electromagnetic radiation in the microwave oscillates so that the peaks/troughs of the wave are constantly flipping. The microwaves themselves don’t technically transfer heat to the food, instead, food typically has polar molecular structures, most commonly water, and the oscillating wavefront causes the poles of H2O molecules to very rapidly spin to align themselves with the changing magnetic field. This spinning of molecules in turn creates kinetic energy in the food because the water molecules bounce off the other molecules in the food, and thus generates heat. As the video shows, there are nodes and anti-nodes inside the microwave which cause an uneven distribution of radiation.
The water molecules are what are oscillating, not the microwaves, and the molecules are not spinning. Spinning (aka rotation) is movement about one degree of freedom, oscillation is movement about two degrees of freedom (and vibration aka translation is movement about three degrees of freedom) - these are strictly defined concepts within chemistry, not to be interchanged. The movement in this case occurs due to a specific absorption band by the O-H bond (created by the particular orbital arrangement and occupation across the O-H bond), and the resulting excitation of the electrons in those orbitals alters the energetic characteristics of the bond, causing rapid shortening and lengthening of the bond - together this movement by both bonds causes the molecular oscillation. It's this creation of kinetic motion which generates the heat that warms food. Source: chemist
@@pizzlerot2730 americas test kitchen had a video on this, where a solid block of ice didn’t melt as much until you added a little water in its liquid state to the top, which helped it melt due to the molecules bouncing and it works much better with a little water.
Lol, I would have just said that microwaves target water molecules, causing them to vibrate, creating friction, thus heat. If you put an empty plate in there it won't heat up😊
You know procrastinating has reached a new level when you're watching a video abt cheese and a microwave instead of studying for your exam that is in an hour
To be a bit more precise: you don't get the wavelength of the microwaves from that experiment. You do however get the wavelength of the formed standing waves. Plus, the main (but not only) contribution to uniform heating is a part called wobbler or stirrer in the microwave that constantly changes vibration modes to counter the build-up of that one standing wave which would give those hot and cold spots. ITs more like a constant shift of where those spots are to put it simple.
@@Deleted11100The center, whether it rotates or not, is always (depending on the microwave unit) going to have a static spot. They're saying that using the rotating center plate (if there is one) 𝙖𝙣𝙙 placing your food off-center on that rotating center plate adds to the movement and interruption, and better coverage, that this video is about.
waait I been putting my stuff in there slightly to the side to accommodate the tilted "splatter shield" I use to cover them just cuz I never wanted to have it fully "on top" so it sits propped at an angle, one end on the spinplate & other over the bowl, leaving just enough room for steam etc to come out, & so that actually helps heat food better?? 🤔
Former audio techie here. We have the same principle in sound waves. Never thought it would apply here too, but it makes sense. One of the many ways this can be solved is not to make rooms with parallel walls. Microwave manufacturers haven't picked up on this.
They have, just not at the entry level. They have diamond stamped interiors for reflection and something called a wave guide and wave stirrer to shoot the waves from the top and reflect them in random directions. Notice how the top of her microwave is one sheet of steel? That means it's a side firing magnetron. The same tech that's in the $50 Walmart special. Look for one with a plastic cover on the roof. That'll be a top firing magnetron with wave guide. It's not exactly new tech either. My LG from 2013 has it and it's amazing. It cost $700 in 2013 money so I can see why not everyone is running out and buying one. But it does exist and has existed for a long time. It's just expensive.
No she just thought you how a microwave heats up, this is a base level explanation of the mechanics of the microwave, hardly a blanket term for “physics”.
Older microwaves seem to do better because, rather than a turntable, they have a spinning waveguide on top. Distributed microwaves more evenly. I rarely have to turn my food manually with my '86 Toshiba.
@@_JustJoe Since ceramic is an insulator, the handle won't get too hot to touch before the beverage boils, so I guess the logic is to prevent a situation where the mug stops on the other side of the tray with the handle facing away. This can be a problem when the microwave is wall-mounted due to lack of counter space, and your mother has only gotten shorter with age.
@@BandlerChing I wouldn't say 'lucky'. It's just better quality product. Given that the video demonstrates why an automatic turntable is NECESSARY, why would any microwave oven be sold without one?! 🤔 It seems you're a little angry. 🤔

Usually if your microwave doesn’t have a spinning platter, there is a mechanism behind the plastic side piece that spins to reflect the radiation pattern in multiple directions
Yea some people think it’s a fan it looks like a metal fan but it’s actually changing the resonant frequency of the microwave cavity. Also I just learned that if your glass gets hot it’s because the glass has a high metal content. Our glass gets so hot without anything in it that it will melt stuff which drove me nuts trying to figure out because plastic will not heat up on its own in the microwave. Try it but maybe not on glass platter. Microwave only eats polar molecules and contrary to popular belief it’s not tuned to resonant frequency of water it doesn’t need to be to heat up polar molecule
I hope people acknowledge there is a Creator and we didn't all come from nothing. Jesus Christ came to reconcile us to God in heaven. The Bible says if we are not for Christ, we are against Him and therefore an enemy of God. Much more important than microwaves and cheese, I promise.
@@johnfal1849 Amen. For God created the stars, the earth, all matter that allows us to use microwaves and all other technology. What we shouldn't do is think that once technology makes our lives easier that we don't need God. Technology can break. The atoms will be here much longer than that.
@@johnfal1849 God and science are not mutually exclusive. If you believe in a creator, then you will only learn more about Him by studying His creation. 🤍
I think sometimes our brains just have a delay. I can not know something I recently learned on an exam but when questioned about it a week later be correct. This could also be because most people have to see the whole picture to understand it’s parts but we typically teach things in small parts before revealing how every fits together. So in short; it’s likely your learning style and their teaching style resulted in your poor retention and understanding assuming you actually tried to learn the material.
To improve uniform cooking you can also cook at a lower power for a longer time. This allows for heat generated at the nodes to redistribute in between pulses. This is particularly helpful when heating dense and/or low moisture foods.
Most microwaves don't actually do " lower power", it's just on for that percentage of time (40% = 4 seconds on 6 seconds off). I've tested this repeatedly, and you can even see and hear it with cheese -- the microwave will hum and the cheese will bubble violently for a few seconds, then it will shut off and the cheese will stop. You can get the same effect by putting your food in for 20-30 seconds, shifting its position, and going another 20-30 seconds, repeating as needed. This means that instead of waiting for convection and radiance to evenly heat your food, you pass all parts of it through the hot spots.
@@CLove511 yep, exactly, when you change the "power level" you are just changing the on/off cycle time. The microwave only ever operates at one output power, you are just allowing time for heat diffusion. If you place your dish off center it will naturally move through the various nodes when the table turns, so you don't have to do that manually.
@@CLove511yeah while i know that the best solution is to take it out and stir it every so often, i still prefer leaving the microwave to do the on-and-off cycle for longer, i am ok with it being a bit less evenly spread out but my hands being free
It is more effective to put the food container close to the outside of the turntable for more even cooking. The magnetron is positioned for best coverage but the middle is not one of the best spots to put food
It's also why you're better off putting the container as close to the side as you can. Helps cover more as opposed to just rotating right in the center.
Then your food is literally cooked unevenly because the waves that are being absorbed by your food are going through a single side and stopping, effectively ruining it.. You're never going to get a better cook from a microwave for your food unless all the food is on that side of the container lol..
Sir, it’s Cheddar cheese &/or Colby cheese+water+salt+cream with sodium citrate added to it… that’s all American cheese is. Sodium citrate is found naturally in many foods. There aren’t any synthetic ingredients involved. Stop with the slander!
This is great education for those who don't understand how it works, fabulous job! What i find with almost anything i cook or heat up is that full power is really bad for most things, every item which says heat on full power for a set time is awful. Regardless of wattage or if im using somebody else's microwave, i always reduce power to around 70% and increase time by 30% approximately and literally everything comes out in better condition than if I'd nuked it on full whack. If you reading this have a neurological condition or just simply fussy with food, I'd recommend you try it. Such a simple adjustment but it's made a sizable difference in my life, it's improved my appeal to the food that comes out because if it isn't just right I'll quite often lob it in the bin.
According to NileBlue, who used chemicals to make it, it is indeed cheese. Just cheddar plus two common food substances, then melted. Its concistendy with the fact that it's cheddar is what makes it... like THAT
@@user-xy1ex2qf6k American cheese ain't even American dude, its like how "hawaiian pizza" is actually Canadian (made by an Italian in Canada) the only reason its called hawaiian is cause of the pineapple, which pineapple isn't even hawaiian either...
Years ago an appliance shop had a little clear plastic box filled with diodes to demonstrate the evenness of the microwaves. You could see the diodes light up and compare the evenness between various microwave ovens.
As an American, I'm not going to defend this product. All I'm going to say is it makes one _hell_ of a grilled "cheese" sandwich. Real American cuisine is questionable fried food that tastes seductively like the diabetes you'll get from eating it.

You can also use the stated frequency from the label on the back of the microwave with the wavelength measured using the cheese to calculate the speed of light.
No can’t you can only measure the wavelength of the stationary wave microwave have a wavelength of about 1 micrometer (one 1000 000 of an eagle’s wingspan for you americans)
@@docteurtnt736 microwave ovens have a wavelength of about 12 cm. Red light has a wavelength in the range of 0.6 to 0.7 micrometers. Microwaves are way different.
I got a new microwave not too long ago and I was baffled when I saw there isn't a rotating plate there, just a fancy bottom. My ancient mind is still trying to figure out how this one works lol
I have an industrial microwave because it was cheap at a closing sale, it's not digital at all, it has a dial like a toaster, it has a bell that dings and it has no spinning plate, just a flat metal bottom It's also way more powerful than a regular microwave, it'll cook an entire frozen lasagna in 6 minutes
I bought a "normal" 1100W microwave from Walmart. At least, the box said 1100 Watts. I got it home, plugged it in, and the CB tripped. I got my clamp-on DMM out and the current flow. It produced 1650W! It worked fine for several years. The pre-determined cooking times had to have an additional 20% of time deducted from the cooking instructions for the food to cook sufficiently. Talk about strange.
I like that you can see why the middle of the food never heats as well because that's the spot of the antinode, but that spot would remain the antinode regardless of spinning. Super cool!
Pretty good basic information. I was an engineer at a microwave manufacturer for 12 years. If anyone wants to know how flat bottom microwaves work, I.e. those without a turntable, remember microwaves can be directed using a rotating waveguide. Cool things microwaves.
Microwave wavelengths ace exactly what they sound like. Micro waves 12 cm(2.4ghz)- 1mm(300ghz)… the wavelength you measure isn’t the wavelength, more like the radiation pattern. Not to mention it’s not just one frequency, flying around in there.
I gave mine up because, for one thing, they kill the nutrients in food. Also, the radiation isn't good for the human body. Any time something is sold as a "convenience", you can bet your booties it's harmful for us. That includes the cell phones we all have.
Here is my theory based on an audio/acoustical perspective. Microwaves have a single frequency of 2.45GHz. I think the hotspots and coldspots are created by the interference pattern of the bouncing waves (bouncing between the walls of the microwave). If the same frequency crosses another one out of phase, it cancels itself out. So you have spots with high amplitudes and low amplitudes. So yeah this creates a standing wave pattern. If a microwave has the length or width of a multiplication of 2.45GHz with a half a wavelength of 12.23cm, standing waves can occur. I could be completely wrong.
thanks for the information! been fixing microwave ovens for years and I actually knew this but now I have understood it even better and clearer. Thanks again.
In my day we walked to school barefoot four miles uphill in a blizzard, and we had to stop the microwave every 30 seconds to hand turn the food. As you can imagine, only 1 in 10 survived early childhood.
@@aredditor4272 True. The commercial microwaves we had at our work did not have the spinning tray and they also were built with a transformer like the old machines. I used to fix them when they would stop working, usually a failed door switch.
@rikkitikkitavi997 Normal water super heats (beyond boiling) under the surface and doesn't show on the surface. Once the surface tension is broken or disrupted, the supe heated water expands violently and usually above the rim of the container and onto your hands. TLDR don't microwave regular water !
this does nothing if the center of the spinning plate is still under your plate. you only changed which part of the plate spins on the spot. It useful with a cup that you can fully place next to the center or you can move the food to the edge of the plate so the middle that spins on the spot is empty.
The spot around the center on the tray is still stationary. This logic would only work if your dish is really small and you put it the furthest possible from the center
In the '80's the Quasar brand was the best microwave oven. At the store they had a large sheet of plastic laminated paper. Under the plastic side, every 3 inches or so, were capsules - evenly spaced across the large laminated paper. You would set the sheet with the capsules in the oven, run the oven and somehow the microwaves would charge up and illuminate the capsules. Without a turntable, Quasar's selling point was that the capsules would all light up evenly, demonstrating even distribution of microwave heat - much better than the rotating table microwaves which really just had a hot spot in one area (the capsules lit up only in one area) and the turntable would rotate the food through that hot spot repeatedly. The even distribution of heat without a turntable was why I bought my Quasar. I guess they had varying frequency/nodes? That microwave oven lasted for about 45 years. Too bad Quasar went out of business. I guess they were too good - didn't break down, requiring a repurchase.
Except for the exceptions. You can divide 985 feet by the ISM (47 CFR 18) allowable and almost uniform frequency of uwave ovens, and know the wavelength. You can then use cheese to guess if you have a (not so common any more) model with a hidden metal fan-like stirrer up top, that randomizes standing waves without a moving platter. In commercial process ovens and consumer models designed to allow for food items that are rather heavy or have awkward shapes and work poorly over cheap rotary platters, the stirrer design is a nice option, also assuming that low overall height but greater interior cooking space height aren't a conflict.
Used this for a lab in college. Except we did it with a layer of chocolate chips or mini marshmallows. If you know the frequency of the microwave (should be labeled somewhere) and a bit of math knowing how the waves behave with the reflections etc, you can actually calculate the speed of light from the wavelength you measured in the hot spots.
I'm pretty sure every microwave on this planet operates at 2450 right in the middle of the ISM band with of course some spillover but the peak should be 2450
Our oven, grill, microwave combo doesn't spin and it came with the house in the before time xD Small stuff gets heated fast. Bowls of bigger stuff you stir halfway through.

This is also why a lot of microwave instructions say to let your food stand for a few minutes before eating it. Partially to prevent you from burning yourself, but also so the hot areas in your food can more evenly distribute into colder areas.

Fr. Didn’t notice the earrings until realizing what the short was talking about.
I always off-center my food... I swear it works better than perfectly in the center.
Because it covers a wider range of wave patterns. I do it too
If you do something like chicken nuggets or anything with multiple pieces, the ones on the edge of the plate get hot faster than the ones in the center. Next time I'll try putting the whole plate all the way to one side and see if that helps.
Bro same I knew I couldn’t be the only one that does that😂
And it still never works

Finally the answer to life’s greatest question. Why tf is my hot pocket cold in the middle.
Always put the food on the side of the spinning tray, not the middle. It helps heating your food more evenly.
Or if the consistency or size of the food allows it, lay it out in a doughnut shape.

microwaving to retain nutes - something new, it is short wave radiation that boils water inside. everything above 50-60 C destroy ANY vitamins and nutrients that are vital to be eaten raw. when they are frozen ice particles penetrate cells and destroy them as well. you eat fiber - that is it@@CarinaCoffee

The difference should be minimal if you are mainly microwaving foods that have already been precooked.
If they are raw materials that is another thing though - microwaves basically just heat the water inside the food turning them into a self contained pressure cooker, but also drying them out which makes them less palatable.

I'm a telecommunication engineer, have studied electromagnetic and microwave, and this woman has made better job in a 60 seconds video explaining it than the countless hours I spent with my profs and colleagues!!!
where exactly have you studied those subjects?
in the university, during my telecommunication engineering years@@ivanivanovich5904
Here is a *simple* explanation of microwaves:
The appliance works by emitting microwaves, which are a type of electromagnetic radiation. These microwaves are absorbed by water molecules in food, causing them to vibrate and generate heat through friction. This heat then cooks or reheats the food. The microwave's metal walls reflect the microwaves, ensuring they mainly target the food rather than escaping into the surroundings.
See? Simple, right? 😮
You needed countless hours to learn the basic idea of a standing wave?
@@Patrick-vv3ig not exactly, but the depth of the understanding remained on the surface, videos like these takes it to the deep level of understanding/visualisation so you can have it right inside your mind, at the end, these concepts should become the base blocks of something more complex

@@Jack_Slate Hey, watch your mouth there! Good, ole, 'murican cheese!!!
Yeah American cheese is just plastic.
@@DreadEnder it’s cheese plus citric acid which keeps the fats from separating from the rest of the dairy and becoming greasy when melted.
For anyone interested, the electromagnetic radiation in the microwave oscillates so that the peaks/troughs of the wave are constantly flipping. The microwaves themselves don’t technically transfer heat to the food, instead, food typically has polar molecular structures, most commonly water, and the oscillating wavefront causes the poles of H2O molecules to very rapidly spin to align themselves with the changing magnetic field. This spinning of molecules in turn creates kinetic energy in the food because the water molecules bounce off the other molecules in the food, and thus generates heat.
As the video shows, there are nodes and anti-nodes inside the microwave which cause an uneven distribution of radiation.
Thank you I was frankly quite frustrated with this video because the reduced explanation could be very misleading.
The water molecules are what are oscillating, not the microwaves, and the molecules are not spinning. Spinning (aka rotation) is movement about one degree of freedom, oscillation is movement about two degrees of freedom (and vibration aka translation is movement about three degrees of freedom) - these are strictly defined concepts within chemistry, not to be interchanged. The movement in this case occurs due to a specific absorption band by the O-H bond (created by the particular orbital arrangement and occupation across the O-H bond), and the resulting excitation of the electrons in those orbitals alters the energetic characteristics of the bond, causing rapid shortening and lengthening of the bond - together this movement by both bonds causes the molecular oscillation. It's this creation of kinetic motion which generates the heat that warms food.
Source: chemist
@@pizzlerot2730 americas test kitchen had a video on this, where a solid block of ice didn’t melt as much until you added a little water in its liquid state to the top, which helped it melt due to the molecules bouncing and it works much better with a little water.
Lol, I would have just said that microwaves target water molecules, causing them to vibrate, creating friction, thus heat. If you put an empty plate in there it won't heat up😊

To be a bit more precise: you don't get the wavelength of the microwaves from that experiment. You do however get the wavelength of the formed standing waves. Plus, the main (but not only) contribution to uniform heating is a part called wobbler or stirrer in the microwave that constantly changes vibration modes to counter the build-up of that one standing wave which would give those hot and cold spots. ITs more like a constant shift of where those spots are to put it simple.
I actually was going to point all of that out.
I am not kidding.
yeah that bugged the shit of me...like why is the screen on the door so much smaller then ??
She mentions that is a standing wave if you watch the video lol
@@jbrizight The standing wave length is not the same as the wavelength of the microwave oven. It's going to be a lower harmonic.
Actually the wave length of a standing wave is the same as the original wavelength. The only things that change are amplitude and phase.

Former audio techie here. We have the same principle in sound waves. Never thought it would apply here too, but it makes sense. One of the many ways this can be solved is not to make rooms with parallel walls. Microwave manufacturers haven't picked up on this.
They have, just not at the entry level. They have diamond stamped interiors for reflection and something called a wave guide and wave stirrer to shoot the waves from the top and reflect them in random directions. Notice how the top of her microwave is one sheet of steel? That means it's a side firing magnetron. The same tech that's in the $50 Walmart special. Look for one with a plastic cover on the roof. That'll be a top firing magnetron with wave guide. It's not exactly new tech either. My LG from 2013 has it and it's amazing. It cost $700 in 2013 money so I can see why not everyone is running out and buying one. But it does exist and has existed for a long time. It's just expensive.

Older microwaves seem to do better because, rather than a turntable, they have a spinning waveguide on top. Distributed microwaves more evenly. I rarely have to turn my food manually with my '86 Toshiba.

@@_JustJoe Since ceramic is an insulator, the handle won't get too hot to touch before the beverage boils, so I guess the logic is to prevent a situation where the mug stops on the other side of the tray with the handle facing away.

Or in my case if your microwave doesn't have a spinning platter it means your platter motor is broken.
Yea some people think it’s a fan it looks like a metal fan but it’s actually changing the resonant frequency of the microwave cavity. Also I just learned that if your glass gets hot it’s because the glass has a high metal content. Our glass gets so hot without anything in it that it will melt stuff which drove me nuts trying to figure out because plastic will not heat up on its own in the microwave. Try it but maybe not on glass platter. Microwave only eats polar molecules and contrary to popular belief it’s not tuned to resonant frequency of water it doesn’t need to be to heat up polar molecule

To improve uniform cooking you can also cook at a lower power for a longer time. This allows for heat generated at the nodes to redistribute in between pulses. This is particularly helpful when heating dense and/or low moisture foods.
Most microwaves don't actually do " lower power", it's just on for that percentage of time (40% = 4 seconds on 6 seconds off). I've tested this repeatedly, and you can even see and hear it with cheese -- the microwave will hum and the cheese will bubble violently for a few seconds, then it will shut off and the cheese will stop.
You can get the same effect by putting your food in for 20-30 seconds, shifting its position, and going another 20-30 seconds, repeating as needed. This means that instead of waiting for convection and radiance to evenly heat your food, you pass all parts of it through the hot spots.
@@CLove511 yep, exactly, when you change the "power level" you are just changing the on/off cycle time. The microwave only ever operates at one output power, you are just allowing time for heat diffusion. If you place your dish off center it will naturally move through the various nodes when the table turns, so you don't have to do that manually.
@@CLove511yeah while i know that the best solution is to take it out and stir it every so often, i still prefer leaving the microwave to do the on-and-off cycle for longer, i am ok with it being a bit less evenly spread out but my hands being free
It is more effective to put the food container close to the outside of the turntable for more even cooking. The magnetron is positioned for best coverage but the middle is not one of the best spots to put food
I always offset my food so it spins around the outside of the plate. Always evenly hot
I do too... I agree it heats up evenly, and also faster.

Very very useful. Keep up the good work
It's also why you're better off putting the container as close to the side as you can. Helps cover more as opposed to just rotating right in the center.
Then your food is literally cooked unevenly because the waves that are being absorbed by your food are going through a single side and stopping, effectively ruining it.. You're never going to get a better cook from a microwave for your food unless all the food is on that side of the container lol..

I bought a "normal" 1100W microwave from Walmart. At least, the box said 1100 Watts. I got it home, plugged it in, and the CB tripped. I got my clamp-on DMM out and the current flow. It produced 1650W! It worked fine for several years. The pre-determined cooking times had to have an additional 20% of time deducted from the cooking instructions for the food to cook sufficiently. Talk about strange.

I like that you can see why the middle of the food never heats as well because that's the spot of the antinode, but that spot would remain the antinode regardless of spinning. Super cool!
Pretty good basic information. I was an engineer at a microwave manufacturer for 12 years. If anyone wants to know how flat bottom microwaves work, I.e. those without a turntable, remember microwaves can be directed using a rotating waveguide. Cool things microwaves.
Microwave wavelengths ace exactly what they sound like. Micro waves 12 cm(2.4ghz)- 1mm(300ghz)… the wavelength you measure isn’t the wavelength, more like the radiation pattern. Not to mention it’s not just one frequency, flying around in there.
It's a ressonating chamber doe, so there kinda really is only one freq (+ harmonics I guess)
Yeah I thought they were only about 3mm for cooking
I gave mine up because, for one thing, they kill the nutrients in food. Also, the radiation isn't good for the human body.
Any time something is sold as a "convenience", you can bet your booties it's harmful for us. That includes the cell phones we all have.
Here is my theory based on an audio/acoustical perspective. Microwaves have a single frequency of 2.45GHz. I think the hotspots and coldspots are created by the interference pattern of the bouncing waves (bouncing between the walls of the microwave). If the same frequency crosses another one out of phase, it cancels itself out. So you have spots with high amplitudes and low amplitudes. So yeah this creates a standing wave pattern.
If a microwave has the length or width of a multiplication of 2.45GHz with a half a wavelength of 12.23cm, standing waves can occur.
I could be completely wrong.

Spinning trays aren't allowed in commercial microwave ovens in food service facilities in many jurisdictions
@@aredditor4272 True. The commercial microwaves we had at our work did not have the spinning tray and they also were built with a transformer like the old machines. I used to fix them when they would stop working, usually a failed door switch.
Sweet demo
The spinning tray is also important when you’re heating water to prevent the water from exploding when you go to remove it.
Too funny
true ! lot of people get burn like that
Water explodes?
@rikkitikkitavi997 Normal water super heats (beyond boiling) under the surface and doesn't show on the surface. Once the surface tension is broken or disrupted, the supe heated water expands violently and usually above the rim of the container and onto your hands.
TLDR don't microwave regular water !
Please for my sanity, BUY A KETTLE. I just dont understand why tf you would microwave water...
What do I do? I'm French, this slice of whatever you call cheese in your hand, is something else here.
I’m torn between appreciating what you showed us, and being horrified at that waste of perfectly good cheese😂
American cheese is not perfectly good cheese. It's trash cheese!
@@ericatucker2683It was still edible though
That’s barely food tho 😂
You’ve never put cheese on a plate and microwaved it before?
Nothing about American cheese is perfectly fine 😂
Genuinely useful
I always put my dish slightly off center on the tray for this reason, so it isnt just spinning on the spot
this does nothing if the center of the spinning plate is still under your plate. you only changed which part of the plate spins on the spot.
It useful with a cup that you can fully place next to the center or you can move the food to the edge of the plate so the middle that spins on the spot is empty.
The spot around the center on the tray is still stationary. This logic would only work if your dish is really small and you put it the furthest possible from the center
In the '80's the Quasar brand was the best microwave oven. At the store they had a large sheet of plastic laminated paper. Under the plastic side, every 3 inches or so, were capsules - evenly spaced across the large laminated paper. You would set the sheet with the capsules in the oven, run the oven and somehow the microwaves would charge up and illuminate the capsules. Without a turntable, Quasar's selling point was that the capsules would all light up evenly, demonstrating even distribution of microwave heat - much better than the rotating table microwaves which really just had a hot spot in one area (the capsules lit up only in one area) and the turntable would rotate the food through that hot spot repeatedly. The even distribution of heat without a turntable was why I bought my Quasar. I guess they had varying frequency/nodes? That microwave oven lasted for about 45 years. Too bad Quasar went out of business. I guess they were too good - didn't break down, requiring a repurchase.
The quasar probably had some sort of fan at the top to scatter the microwaves coming from the magnetron at the side via a waveguide to the top
Those capsules were neon bulbs
For the non American viewers, does this work on real cheese?
No you must have plastic cheese
@@TsarFrancisDrakehaha! How’s that irony deficiency going? You can get pills for that ;)
I was wondering that too? 🧀😂
@@TsarFrancisDrake wow thanks that makes it sounds even less palatable! Jesus wept.
have you ever tried the brown stuff they call chocolate over there?
avoid at all costs.
Love that your ear rings are standinf waves 😊
*SIS CALLED ME STUPID IN MICROWAVE LANGUAGE*
What an actual interesting way to tell the good spots of a microwave, you not onky get to know the results but also free plastic cheese too!
Excellent demonstration! You can even calculate the speed of light based on this! :)
How?
You could. But most people just eat the food.
Great demo.
Except for the exceptions.
You can divide 985 feet by the ISM (47 CFR 18) allowable and almost uniform frequency of uwave ovens, and know the wavelength. You can then use cheese to guess if you have a (not so common any more) model with a hidden metal fan-like stirrer up top, that randomizes standing waves without a moving platter.
In commercial process ovens and consumer models designed to allow for food items that are rather heavy or have awkward shapes and work poorly over cheap rotary platters, the stirrer design is a nice option, also assuming that low overall height but greater interior cooking space height aren't a conflict.
Used this for a lab in college. Except we did it with a layer of chocolate chips or mini marshmallows. If you know the frequency of the microwave (should be labeled somewhere) and a bit of math knowing how the waves behave with the reflections etc, you can actually calculate the speed of light from the wavelength you measured in the hot spots.
Or a chocolate bar, in honor of the guy who figured out the phenomena with a candy bar in his shirt pocket.
I'm pretty sure every microwave on this planet operates at 2450 right in the middle of the ISM band with of course some spillover but the peak should be 2450
Although I would like to know if anyone has made a 5GHz microwave as the wavelengths are shorter and theoretically heating should be more even
Our oven, grill, microwave combo doesn't spin and it came with the house in the before time xD
Small stuff gets heated fast. Bowls of bigger stuff you stir halfway through. Which you need to do anyway with stuff from the refrigerator.
It also isn't built to self destruct after 3 years, so it still works perfectly.
Doesn't have a billion buttons or programs either. Just time, temperature and go. I love it.
Dread the day that it dies and we need to buy a new one.
We have a professional microwave that used to cost 4000 euros 20 years ago. It has 4 buttons and no spinning plate and it heats up even big plates evenly
Hopefully by then more sustainable alternatives will be made available.
Excellent explanation
Very interesting:)
WOW, this is absolutely life changing stuff. Watching this ever so informative video has made me realise it's bedtime 😂
Not only that .... but that cheese, looks so natural, and so yummy ... americans uh? LOL
I'm in the kitchen right now measuring my cheese 😅
Pro tip, put your plate closer to the side for even better heating
Very educational video, thanks
