It's actually the speed it travels. I can see it in my TV screen when there's a bright red it stands out, if it's blue, it fades back. Both like a 3D image. It's called the red shift which is how they determine if certain stars are traveling away from us and at what speed. It's really neat to see red and blue next to eachother on your tv screen.
@Garry Kennedy No, it's the wavelength or frequency. The amount of hertz (cycles per second) is different, I don't think the speed it travels changes at all. Just the speed it oscillates.
@@urphakeandgey6308 So you think it's like a carrier frequency that information travels on? Not sure how that affects the Red standing out on my TV screen where as the blue looks sunk in. My brother doesn't see this effect, but I wear glasses and he doesn't. Not sure how or if that affects the effect. But it's very definitive to me. So that would mean that lower RF frequencies travel at the same speed as UHF? This is interesting to me. I've studied the effects of lower frequencies characteristics as being able to travel through obstacles better than higher frequencies bouncing off of the same obstacle in my attempt to understand my 5.8GHz video transmitter vs a 900MHz ability to travel farther distances at a loss of time it takes to reach my RX goggles during first person view flight.

@Gabriel Neipp You didn't have to write a long essay on that. I was quite disturbed on how you made such quick assumptions on that old lady just coz you passed 5thGraDe.
Yes, Oh Yes! OMG around 6:28, when he looks around and realizes what colors are, it's so beautiful, you can see the amazement in his eyes! This is why I love teaching these things to people, instead of mocking them for not knowing. You see them realize how beautiful the world around them actually is, and it's an awesome sight! Cheers!
Not only how amazing the world is, but how amazing understanding the world is in actuality. Nature is beautiful, and Feynman proclaimed this perfectly: "I have a friend who's an artist and has sometimes taken a view which I don't agree with very well. He'll hold up a flower and say "look how beautiful it is," and I'll agree. Then he says "I as an artist can see how beautiful this is but you as a scientist take this all apart and it becomes a dull thing," and I think that he's kind of nutty. First of all, the beauty that he sees is available to other people and to me too, I believe. Although I may not be quite as refined aesthetically as he is ... I can appreciate the beauty of a flower. At the same time, I see much more about the flower than he sees. I could imagine the cells in there, the complicated actions inside, which also have a beauty. I mean it's not just beauty at this dimension, at one centimeter; there's also beauty at smaller dimensions, the inner structure, also the processes. The fact that the colors in the flower evolved in order to attract insects to pollinate it is interesting; it means that insects can see the color. It adds a question: does this aesthetic sense also exist in the lower forms? Why is it aesthetic? All kinds of interesting questions which the science knowledge only adds to the excitement, the mystery and the awe of a flower. It only adds. I don't understand how it subtracts."
I also find it fascinating how he is the only person who answers "good question" instead of trying to make up something (and fail of course, you never know until you know)
And here I am, ten years after this was posted, it is still the best explanation of the double slit experiment ever! Now I need to find the episode where you conclude that light also has to be a particle. And then the one where the existence of a photon is dependent on an object it "hits".
Itotally get it. Itsamazing to see aomeone learn something awesome like that. I once explained the size of the universe to my 4 year old nephew and right after he looked up at the sky and said woooaaaahhh!
The guys reaction in the yellow shirt and blue hat- literally made my day! It’s so rare to observe someone genuinely experiencing amazement. It really is one of the purest forms of joy. So human. So awesome:)
Their reaction shows the difference between making something interesting, and what schools do. All these people made this experiement in school I bet, and nobody even remembers doing it. I learned this in 10th grade. But schools make everything so boring and make everything be a chore that nobody WANTS to learn it. We really need to change the way we teach things, because currently we are just wasting our kids' time.
The man in the yellow shirt almost made me cry of joy, because it was the most beautiful example of human curiosity and wonder for nature itself that I have ever seen. He was absolutely amazed by what he saw, inmediately proceeded to communicate his experience but the joy that the experience brought to him wouldn't let him wait to see it again, and then the best thing that ever happened to the Universe: the man asked why. That in that order has to be the most beautiful set of emotions that anyone can go through.
Your coment is unscientific. In fact there are resurch that show how our body and mind actually generate wave lengths in various frequencies. Other resurch shown that people cane experience synesthesia (a mix of the senses). Why not an implefyed sences? The door is open for the deconstruction of preconceved ideas of the world. This is scientific...
@@sunseb5124 you have not provided any back up information or sources and you are like that guy that says they are not religious but they are spiritual. Ya jackass
Actually, the video does not mention that you won't have a "wave pattern" if you use two sources of photons (with the slices). In his experiment on the water, he's using two sources of waves. Particles would not interfere if we did that with light. It looks like a detail but it's a big difference if you really want to understand QM.
Thanks Veritasium! I was recently studying diffraction for my college entrance exam, and you helped me envision how the double slit experiment actually looks like. This is gonna help me build my concepts
Bhai I am also a Jee aspirant , how ever case performed in this video is a special case because a whitle light consists of various colour with different wavelengths so the is only once central maxima whereas the colour spots are due to individualistic wavelength.
@@prashand4899 you dont know if he spends his time learning about other things. Physics isnt limited to the double slit experiment and you can study branches without learning about it.
Being a highschool student, I took personal interest in the double slit and double hole experiment, and how it explains more than just the nature of em waves, from which I mean how it explains the many worlds interpretation and the hypothesis of the universe effortlessly preventing the collision of wave function I wont elaborate the discussion here but you van find many youtube sources explaining such
A lot of people just react with complete disinterest. I think those people unfortunately can't really be helped. But the yellow shirt guy was clearly fascinated. It's a good way to be.
Just learnt about YDSE today in school, and came back to watch this video. Crazy how great quality it is, even though it was made 10 years from now! You're amazing, Derek!
Years later people would describe Derek as the man who roamed the streets and talked physics with commoners like philosophers used to, about a few thousand years ago
Except Socrates and philosophers were not meddling with questions pertaining to empirical science. So the comparison only goes so far as him asking questions but not the actual nature of the knowledge or wisdom sought. Philosophy is the love of wisdom and seeks the knowledge of first principles and being as being and the nature of things. Philosophers are not empirical scientists. If I ask what is the nature of water as a philosopher I do not care about it being H2O. That is the realm of chemistry not philosophy.
@@optimoprimo132 well, yes i totally agree... but as you probably know, philosophy and empirical science are sets that intersect, simplistically speaking, its probably more complex than that.... but for example the great mystery: consciousness. well you see things because light falls on your retina, the rods and cons pick those signals up, the optic nerve converts those signals to electrical impulses that then goes to the visual cortex to be processed, and we see it, that sight or the image in our mind can produce different effects, if its a tiger on loose that a person sees, adrenaline and the other hormones get released and speed up the heartbeat, he escapes. this becomes a part of the memory in the hippocampus, and that person tells the story to the others cuz of psychology, he feels the need to share this with everyone, so that he can connect with them, etc..... science seems to creep up in every single question we ask, but even physicists and biologists realize, its not a complete understanding of everything. that person who experienced all that, who is he? is he just a symphony of these synchronized processes, or is they deeper than that.... consciousness is something that cant be explained by the theory of synchronized neurons firing at the right time. just like if you successfully create a simulation of an ocean, by coding all the movements of the water molecules, all of the factors, the environment, the whirlpools, the currents,... the simulation will still be missing the essence, the wetness, its still not real water
Another do-it-at-home experiment that amazed me concerning interferences : Sound interferences. Take 2 loudspeaker (= 2 slits), place them 1 m appart and play one tone (= 1 Wavelenght) . As you move around the loudspeakers you will find dark zones (quiet) and bright zones (loud). Couple of softwares are available on the internet to play around.
@@OhFishyFish still in the middle of the video but aren't waves just another modell like beams? I though they were quantum particles ( excuse my english)
What I like in these videos is the sheer amazement of people when they get the explanation. They're not stupid, they just don't have the same interests nor fields of competences than what the video is about. But they're glad they've learned something and in the end, it's not being smart or stupid that counts, it's learning new things and seeing how cool the world really is.
what concerns me a little is some people would create some nonsense instead of admitting they dont understand something. admitting ignorance is good (ignorance is normal), but pretending to know the answer is not good.
Shaurya Shubham nor so sure that everyone is a genius, but I've met people who were geniuses at having fun... WOW! I've met one who was a genius at having sex, that was heartbreaking... But no, I'm not a genius at anything. Just have a thirst for knowledge and understanding.
A correction. We are all stupid humans, on a cosmic scale there is no difference of intellect between any humans. However some humans are more experienced/trained in some local areas than others. Also, some humans don't train their brain as much as others. This leaves room for diversity of brain activity 😉 ignorant is usually more correct than stupid, but both terms have their use.
Honestly, I have seen numerous videos and been taught this multiple times before in class, but this video was the one that finally had me understand it. All of the other ones kept going into abstracts over light as a wave, but simply demonstrating it and then showing it on a pond was what actually helped it click for me.
Derek! You're SO INCREDIBLE to able to show the interference - the most complicated topic in school physics. And you're able to find the simpliest way to explain this. I'm amazed that you have opportunities to see the original manuscripts of great psicist! Just WAU!!! Incredible!!!
The truly mindblowing part of this wasn't even discussed. When you measure any of the photons individually, they all pass through a slit as a particle. The implications of this experiment are beyond fascinating. Quantum physics is trying to tell us that all possible scenarios exist all the time. Our experience as an observer is what determines the path we're experiencing.
Simple answer. Light is like a water, opposite. Depends on how you oberve/interact. They can be looks like particle, or wave Water can moving like a wave. But its particle Light can moving like a particle, but its a wave
@@allvid_ What if I told you that it's the wave using water, causing the water particles to vibrate but not the water itself. Whereas, it's the actual light which has wave or particle property rather than a wave just using it as a medium? 😭
@@chanella3996 I often wonder if we are the shadow of another dimension, limited by this dimension we call space time continuum; and if there is a way to enter that dimension and perhaps travel faster than light in a vacuum. Imagine sound waves traveling through steel rather than air.
I m in 12th class so according..to me its a wavelength ....bcz if we pass colour light through class slab. .its frequency wiilll remain same but Wavelength will change..but still color reamain same thats why frequency is characteristic of light
You left out the best part of the experiment! What mind blowing is that when the light is measured after it passes through the slit, it no longer creates the wave pattern! Meaning the act of measurements turns the wave back into a particle. Einstient proved this with the photoelectric effect, and as said, the double slit was redone with measurements to show that light can act as a particle. Essentially light is only a wave pattern when it's not interacting with anything, when it does interact it becomes a discreet particle. One of the coolest revelations in physics.
I've heard the the waves are 'probability waves' in that they are caused by the probability of photons either going into one slit or the other and then the interference of those waves causing that pattern. So light is really photons but the path those photons take is a matter of probability thus causing them to behave like waves...or something like that.. Something to do with the uncertainty principle.
I LIKE the guy in the yellow polo shirt. He's showing the right kind of response to stuff this fascinating. He strikes me as someone that would get sucked in if he started to learn some of this stuff.
Well, she is kind of right. Photons are a fundamental particle. I think that is what she was getting to. The standard model is sometimes called the physicist's periodic table.
@@Moonlakes Photons, which is the stuff light is made of, are elementary particles. So here is the comparison: elementary particles (like photons) are for the standard model of particle physics what elements are for the Mendeleev's periodic table. Do you really think she thought light is like oxygen? Of course not. She was saying, in a layman's way, that inferring to photons being an elementary particle.
Guys, don't hate on the people with the silly answers. They (maybe) learned this stuff years/decades ago. They haven't thought about it since. They probably know things we don't and think we're silly for not knowing. Except the chakra lady. She knows nothing.
This is the best explanation of this concept so far. It's always important to have a proper visualization of each concept. Even if someone isn't familiar with quantum physics, this is the perfect way to visualize the experiment.
I was lucky to conduct such experiments when I was so young, 75 years ago. The time gap between 3:24 and 3:52 showing the Yellow shirted man keep going back to see the wonders behind the double split experiment, somehow touched me emotionally, as, effectively, there was a blind man who suddenly began to see the hidden wonders of science, at his age, and slowly began to conceive that there are so many wonderful, majestic activities and processes behind the silence and unlit spaces around us! I loved it when his keenness to learn, and his thirst for more, he forgot about his cap, paused, and quickly corrected the situation, yearning for another opportunity to behold the miracles around him which he never saw before.
That feeling. Life without it is such a waste of time. Everyone is born with this curiosity and fascination and has it as an infant and and later as a kid but most of us lose it later somehow. Keeping it and learning to live with this feeling of excitement of reality around us should be part of the education goals.
It saddens me that there are people who would rather believe in religious dogma and outright ignore science. Because of their beliefs, they have a blatant non-willingness to learn, and because of that, will never see the beauty of science around them. It’s a truly wonderful thing to behold the evidence of science before your eyes, and realizing it has nothing to do with or without a creator; it just is because that is how nature works.
In the experiments of Huygens/Young ,there was no evidence that the claimed interference patterns were not a reflection of mechanical particles toward the back walls reflecting further onto the front walls. They simply assumed that since we see an interference pattern of light on the side of the slits ,that meant that light only was a conglomerate of wave energies. He forgot that photons do not necessarily only enter straight through the slits nicely. From there one went on to the idea of the wave particle duality. (particles only appear if there is only a wave and we look at it) Of course it is way more plausible that the spin mechanics cause the waveform. You will find nobody in CERN agreeing that particle spin doesn't occur... Many particles travelling in a large speed cannot make us detect the pathway perfectly, but it will certainly appear as a wave.
@@acidplasticine What fascinates me about humans is that most are driven by their instincts and their emotions and some are driven by their minds. Though there is no shame in being driven by instincts and emotions the world does not advance much with people driven by their instincts and emotions which are basically irrational and illogical.
@@JanoyCresvaZero It is such a pity that there are many people who like to compete against their fellow humans and they spend all their life exploiting society in earning their living pitting their wits against fellow humans, just distributing emotions to them! Since not so long time ago some people became aware of the wonders behind the silent and invisible processes and activities in the universe and that what we may call science and engineering and mathematics where the latter may not be a natural phenomenon but their operators are very rational, logical and reasoned out rather than dealing with the instincts and emotions of people and social services where all that matters is catering for instincts and emotions. Religions and politics did not do much for the tangible guaranteed comforts of the family and it is when science took over from the emotions of art and religions that the family gained so much to have all the practical tangible guaranteed comforts we now have during our life and not after death.... al because the logic in engineering replaced the emotions in art and religions and politics and other " unguaranteed social services!".
To make the experiment more compelling, they should allow the subjects to look through the box with only one slit open. After they see, ask them what they think is going to happen when they open the other slit (the second slit). That way the can truly see the difference between them. But still an awesome video.
This is a really great explanation of the original experiment. The hard part comes when we use particles, they exhibit the same properties even when shot one at a time.
The even harder part is finding any experiment that performs the next step people talk about which is, when one of the slits is observed, the particles go back to acting like particles. I can't find a single source or experiment that does this, yet hundreds of articles and people are talking about it.
Class 12 from India hit like 🙋🏻♀️ But seriously man, the way they teach these subjects in school sucks all the fun out of it. I hope we can have more teachers like these guys who make learning fun for everyone.
It’s amazing to me that there are people who aren’t aware of the experiment at this point. Crazy how knowledge and understanding can be taken for granted. Also Interesting to think of these types of interference in relation to sound waves waves
The guy in the yellow shirt made me understand why people become teachers. He literally shone up like a child, inspired and awestruck by the beauty of nature and physics, and just kept on asking questions on the nature of light. It was amazing to watch!
this created a lot of interest. Think how many young people would start considering after seeing demos like this when young? The World would get many new physicists and mathematicians in no time.
It took 7 years for RUclips to consider me worthy of viewing this video.... The school taught me this 8 years ago, I didn't understand it back then but now I can...

I'm at highschool, doing my physics presentation about light diffraction right now, and this video is absolutely amazing, best explanation I've found so far!
It's not. Does not explain why the pattern happens. Nothing about the surface of those slits difracting photons causing them to interact with each other. Also the wave-like function is there bc billions of photons pass through the slits in a second. If only one photon was shot through you would see one dot as if it was detected by a detector.
@@va_nda Nope it does, that water waves demonstration was all that was needed to understand the principle reason behind ydse/ interference. But yes it isnt enough to study deep into the topic
I love you videos .. seriously !! I am from India an eighteen year old lad, we have this for our highschool and we didn't had the experiment live or with this simplicity explained to us due to covid regions (college being closed) ..and this video gave me the knowledge I needed and also a urge and excitement to know more and more and explore about the amazing field of science
One of my most exciting art experiences was seeing Michelangelo's sketches for paintings in real life.

At the same time, I see much more about the flower than he sees. I could imagine the cells in there, the complicated actions inside, which also have a beauty. I mean it's not just beauty at this dimension, at one centimeter; there's also beauty at smaller dimensions, the inner structure, also the processes. The fact that the colors in the flower evolved in order to attract insects to pollinate it is interesting; it means that insects can see the color. It adds a question: does this aesthetic sense also exist in the lower forms? Why is it aesthetic? All kinds of interesting questions which the science knowledge only adds to the excitement, the mystery and the awe of a flower. It only adds. I don't understand how it subtracts."

I also find it fascinating how he is the only person who answers "good question" instead of trying to make up something (and fail of course, you never know until you know)

And here I am, ten years after this was posted, it is still the best explanation of the double slit experiment ever! Now I need to find the episode where you conclude that light also has to be a particle. And then the one where the existence of a photon is dependent on an object it "hits".
Hi it is a very fascinating experiment

The guys reaction in the yellow shirt and blue hat- literally made my day! It’s so rare to observe someone genuinely experiencing amazement. It really is one of the purest forms of joy. So human. So awesome:)
Their reaction shows the difference between making something interesting, and what schools do. All these people made this experiement in school I bet, and nobody even remembers doing it. I learned this in 10th grade. But schools make everything so boring and make everything be a chore that nobody WANTS to learn it. We really need to change the way we teach things, because currently we are just wasting our kids' time.
The man in the yellow shirt almost made me cry of joy, because it was the most beautiful example of human curiosity and wonder for nature itself that I have ever seen. He was absolutely amazed by what he saw, inmediately proceeded to communicate his experience but the joy that the experience brought to him wouldn't let him wait to see it again, and then the best thing that ever happened to the Universe: the man asked why. That in that order has to be the most beautiful set of emotions that anyone can go through.

@@optimoprimo132 well, yes i totally agree... but as you probably know, philosophy and empirical science are sets that intersect, simplistically speaking, its probably more complex than that.... but for example the great mystery: consciousness. well you see things because light falls on your retina, the rods and cons pick those signals up, the optic nerve converts those signals to electrical impulses that then goes to the visual cortex to be processed, and we see it, that sight or the image in our mind can produce different effects, if its a tiger on loose that a person sees, adrenaline and the other hormones get released and speed up the heartbeat, he escapes. this becomes a part of the memory in the hippocampus, and that person tells the story to the others cuz of psychology, he feels the need to share this with everyone, so that he can connect with them, etc..... science seems to creep up in every single question we ask, but even physicists and biologists realize, its not a complete understanding of everything.
that person who experienced all that, who is he? is he just a symphony of these synchronized processes, or is they deeper than that.... consciousness is something that cant be explained by the theory of synchronized neurons firing at the right time. just like if you successfully create a simulation of an ocean, by coding all the movements of the water molecules, all of the factors, the environment, the whirlpools, the currents,... the simulation will still be missing the essence, the wetness, its still not real water

What I like in these videos is the sheer amazement of people when they get the explanation. They're not stupid, they just don't have the same interests nor fields of competences than what the video is about.
But they're glad they've learned something and in the end, it's not being smart or stupid that counts, it's learning new things and seeing how cool the world really is.
what concerns me a little is some people would create some nonsense instead of admitting they dont understand something. admitting ignorance is good (ignorance is normal), but pretending to know the answer is not good.
Shaurya Shubham nor so sure that everyone is a genius, but I've met people who were geniuses at having fun... WOW! I've met one who was a genius at having sex, that was heartbreaking...
But no, I'm not a genius at anything. Just have a thirst for knowledge and understanding.
A correction. We are all stupid humans, on a cosmic scale there is no difference of intellect between any humans. However some humans are more experienced/trained in some local areas than others. Also, some humans don't train their brain as much as others. This leaves room for diversity of brain activity 😉 ignorant is usually more correct than stupid, but both terms have their use.
I'm actually really amazed that none of those people didn't know about that. I thought everybody should know this since school.

Honestly, I have seen numerous videos and been taught this multiple times before in class, but this video was the one that finally had me understand it. All of the other ones kept going into abstracts over light as a wave, but simply demonstrating it and then showing it on a pond was what actually helped it click for me.
You were probably looking at sketches of this same thing and just never got the gist.
@@gileee That's exactly why experiments are the best way to learn.
Derek! You're SO INCREDIBLE to able to show the interference - the most complicated topic in school physics. And you're able to find the simpliest way to explain this. I'm amazed that you have opportunities to see the original manuscripts of great psicist! Just WAU!!! Incredible!!!
The truly mindblowing part of this wasn't even discussed. When you measure any of the photons individually, they all pass through a slit as a particle. The implications of this experiment are beyond fascinating. Quantum physics is trying to tell us that all possible scenarios exist all the time. Our experience as an observer is what determines the path we're experiencing.
Simple answer. Light is like a water, opposite. Depends on how you oberve/interact. They can be looks like particle, or wave
Water can moving like a wave. But its particle
Light can moving like a particle, but its a wave

@@allvid_ What if I told you that it's the wave using water, causing the water particles to vibrate but not the water itself. Whereas, it's the actual light which has wave or particle property rather than a wave just using it as a medium? 😭

I m in 12th class so according..to me its a wavelength ....bcz if we pass colour light through class slab. .its frequency wiilll remain same but Wavelength will change..but still color reamain same thats why frequency is characteristic of light
"What is this?"
"It's a blue light."
"What does it do?"
"It turns blue."
(Rambo 3)
You left out the best part of the experiment!
What mind blowing is that when the light is measured after it passes through the slit, it no longer creates the wave pattern! Meaning the act of measurements turns the wave back into a particle.
Einstient proved this with the photoelectric effect, and as said, the double slit was redone with measurements to show that light can act as a particle.
Essentially light is only a wave pattern when it's not interacting with anything, when it does interact it becomes a discreet particle.
One of the coolest revelations in physics.
I've heard the the waves are 'probability waves' in that they are caused by the probability of photons either going into one slit or the other and then the interference of those waves causing that pattern. So light is really photons but the path those photons take is a matter of probability thus causing them to behave like waves...or something like that.. Something to do with the uncertainty principle.
Dennis Santos Actually light is both a wave and a particle. It's called particle-wave duality. Same happens with most of subatomic particles.

This is the best explanation of this concept so far. It's always important to have a proper visualization of each concept. Even if someone isn't familiar with quantum physics, this is the perfect way to visualize the experiment.
The dude with the cap was so genuine.
I was lucky to conduct such experiments when I was so young, 75 years ago. The time gap between 3:24 and 3:52 showing the Yellow shirted man keep going back to see the wonders behind the double split experiment, somehow touched me emotionally, as, effectively, there was a blind man who suddenly began to see the hidden wonders of science, at his age, and slowly began to conceive that there are so many wonderful, majestic activities and processes behind the silence and unlit spaces around us! I loved it when his keenness to learn, and his thirst for more, he forgot about his cap, paused, and quickly corrected the situation, yearning for another opportunity to behold the miracles around him which he never saw before.
That feeling. Life without it is such a waste of time. Everyone is born with this curiosity and fascination and has it as an infant and and later as a kid but most of us lose it later somehow. Keeping it and learning to live with this feeling of excitement of reality around us should be part of the education goals.
It saddens me that there are people who would rather believe in religious dogma and outright ignore science. Because of their beliefs, they have a blatant non-willingness to learn, and because of that, will never see the beauty of science around them. It’s a truly wonderful thing to behold the evidence of science before your eyes, and realizing it has nothing to do with or without a creator; it just is because that is how nature works.
In the experiments of Huygens/Young ,there was no evidence that the claimed interference patterns were not a reflection of mechanical particles toward the back walls reflecting further onto the front walls.
They simply assumed that since we see an interference pattern of light on the side of the slits ,that meant that light only was a conglomerate of wave energies. He forgot that photons do not necessarily only enter straight through the slits nicely. From there one went on to the idea of the wave particle duality. (particles only appear if there is only a wave and we look at it) Of course it is way more plausible that the spin mechanics cause the waveform. You will find nobody in CERN agreeing that particle spin doesn't occur... Many particles travelling in a large speed cannot make us detect the pathway perfectly, but it will certainly appear as a wave.
@@acidplasticine What fascinates me about humans is that most are driven by their instincts and their emotions and some are driven by their minds. Though there is no shame in being driven by instincts and emotions the world does not advance much with people driven by their instincts and emotions which are basically irrational and illogical.
@@JanoyCresvaZero It is such a pity that there are many people who like to compete against their fellow humans and they spend all their life exploiting society in earning their living pitting their wits against fellow humans, just distributing emotions to them! Since not so long time ago some people became aware of the wonders behind the silent and invisible processes and activities in the universe and that what we may call science and engineering and mathematics where the latter may not be a natural phenomenon but their operators are very rational, logical and reasoned out rather than dealing with the instincts and emotions of people and social services where all that matters is catering for instincts and emotions. Religions and politics did not do much for the tangible guaranteed comforts of the family and it is when science took over from the emotions of art and religions that the family gained so much to have all the practical tangible guaranteed comforts we now have during our life and not after death.... al because the logic in engineering replaced the emotions in art and religions and politics and other " unguaranteed social services!".
To make the experiment more compelling, they should allow the subjects to look through the box with only one slit open. After they see, ask them what they think is going to happen when they open the other slit (the second slit). That way the can truly see the difference between them. But still an awesome video.
Try it with electrons instead of photons, you'll have the same pattern even with only one slit open
ruclips.net/video/J_t380X1_2A/видео.html
This is a really great explanation of the original experiment. The hard part comes when we use particles, they exhibit the same properties even when shot one at a time.
The even harder part is finding any experiment that performs the next step people talk about which is, when one of the slits is observed, the particles go back to acting like particles. I can't find a single source or experiment that does this, yet hundreds of articles and people are talking about it.

I found your channel today, and have now watched quite a few, and I've nothing to say except........you are freaking awesome at getting your point across to the peops who don't yet know....but I've learned from you, and i'm not dumb and uneducated......I've subscribed simply, because you're FANTASTIC at what you are trying to achieve. And I thought I knew everything - you proved me and my fam wrong !!! :-)
Rinn Sl4ck Thank you?
ArrKayCee I thought the point was to educate people
Nicholas Staines very well put
I'm at highschool, doing my physics presentation about light diffraction right now, and this video is absolutely amazing, best explanation I've found so far!
It's not. Does not explain why the pattern happens. Nothing about the surface of those slits difracting photons causing them to interact with each other. Also the wave-like function is there bc billions of photons pass through the slits in a second. If only one photon was shot through you would see one dot as if it was detected by a detector.
@@va_nda I mean sure but the experiment was to just show a very simple concept to the average person, not a physics student.
@@va_nda Wrong. One photon would still produce an interference pattern.
What does only one slit produce in the box? I.e. no second slit for the "waves" to overlap.
@@va_nda Nope it does, that water waves demonstration was all that was needed to understand the principle reason behind ydse/ interference. But yes it isnt enough to study deep into the topic
I HAVE BEEN ENLIGHTENED
Pun intended?
So is it particle or wave?
I guess this vid LIGHTENED up your day
YOU DID NOT!!
quite delightful wasn't it
Channel so good... Even rajwant sir watches it
The happiness of that Scottish guy inspires me.
You go inside a square ring and fight someone with punches only.
The dude in the yellow shirt is awesome, he's so stoked on the whole thing!
I love you videos .. seriously !! I am from India an eighteen year old lad, we have this for our highschool and we didn't had the experiment live or with this simplicity explained to us due to covid regions (college being closed) ..and this video gave me the knowledge I needed and also a urge and excitement to know more and more and explore about the amazing field of science
बहुत ही अच्छे से समाझाये है प्रकाश की दैत्य प्रकृति को।
Nice 👌👌

The Deaner no only difference is their wavelength and energy
Light is only form of energy having certain wavelength and has dual nature
@@devkumar9889 wooooooosh
I like that you can see he’s getting emotional reading the notes in the vault. What an experience that must have been!
One of my most exciting art experiences was seeing Michelangelo's sketches for paintings in real life. For some reason I don't really care about the fully rendered color paintings, but the minimalist sketches with just a few lines blew me away. I bet it could be something akin to that experience, seeing the actual original from the man himself.
What do you mean “ notes in the vault “ ?
@@MAsWorld1 at the beginning they go into a vault and read the original hand written experiment from 1803

He should win an award for worst explanation ever.
I laughed so hard at that XD

***** Wasn't he so humble on that? :P

XDDDDDDDDDDDDDDDDDDDDDDDDDDDD
Ten years ago when I was still a teen, I didn't understand a thing about this video, yet still got mesmerized by it. Now I'm already in my late 20s, I got even more mesmerized by it.
very interesting indeed, im sure we have only begun to scratch the sufrace
"There's some kind of principle... That the average person is not familiar with" this guy is right on 😂
Just seeing people’s reactions made me love a-level physics
No. A level physicis is a very underwhelming curriculum to learn science. Go straight to learning with the undergrads and you won't regret
Veritasium: What's the difference between blue light and red light?
Random Guy: The color
Veritasium: Understandable, have a nice day.
technically he's right but it can be more complicated than that.
this is by-far the best authentic explanation of the YDSE such that anyone could understand. this is a masterpiece
