If you measure a ‘white’ LED with a spectrometer, you’ll see it’s made up from primarily yellow and a bit of blue, as verified by the data sheets. There no such thing as a full spectrum LED at least yet. This may be a confusing point to those new to the world of photonics. I used to build Quantum Efficiency devices to measure the efficiency of solar cells of all sorts, and can arrest to the value of LEDs in this undertaking.
GreenAppelPie, check out yuji LEDs. Their spectrography show a pretty solid spread for both 6500k and 3200k at 98 cri a and equally hich TCLI. Of course, that is the phosphor impregnated silicone and not the actual emmiter which is UV (as opposed to typical 450nm).
Keystone Science their full name is "the thought emporium" he can be found here: ruclips.net/user/TheChemlife He does tons of facinating experiments, like you do, and I would love to see a colab. Thanks for actually checking the comment section, and keep up the great work!
Hey Keystone, I have something u may be interested on. Over 0.016A Flowing through your body is where we can no longer let go. 0.05A is lethal and 0.1A can stop your heart. But resistance in our body blocks the current flowing in us, here's how: Voltage÷YourResistance×Current or (V÷BR×A) For Ex: My body Resistance is 180KOhms, and I touch an AC outlet of 120V and 10A. How am I not dead? It's because there's 6mA out of 16mA flowing, which is not lethal enough.
Your choice to use a 532mm green laser for measurement was a good one. Green lasers use a technology called DPSS, which doesn't change its wavelength based on temperature.
Awesome! I shot a laser level at my phone lense and you can see the difference in the wave pattern of the 650+ nano meter wave length in 360°. Basically, I snapped a picture of the reflection on the lense and named it "the double slit 2.0." too bad we can't post picks in the comment section or i'd gladly share it with every one.
Great video! So a topic for future videos? Could you show how to do the math for a circuit? I know all about series and parallel resistors and capacitors, I know the gain of a transisyor, pretty much, but I dont know anything outside of that, and how do you put it all together to figure out the maths for an actual circuit?? That would be an awesome video!
I have a question........Do all LED lights flash or strobe so fast that our eyes can't see them flash......they just look like they are one constantly?......if so.....do they all flash at a different rate?......what is the rate in which our eyes stop seeing the flashes?.....thnx for all of your great videos!!
Hey, its been a while? I miss your content!! Also, sorry to hear about the whole fusor situation, I guess producing a 100 billion neutrons/second is safe( or legal). Hope you and cody could do a different collaboration.
Doesn't the graph imply that a 0 eV energy photon still has some wavelength? I think that fit really has to be forced through (0,0) for it to make sense.
May we see a video regarding the manipulation of plasma with electromagnetic fields in the future? I'm looking for information, and can't find a whole lot of it.
I have a question: If everything is made up of particles, or quanta, then what is a magnetic field? I’m not asking for a description of what that field does but rather what physical quantum particles actually make up the field.
Honestly, I, nor really any one knows, some people theorize that it is a product of particles, like the theorized graviton, however this should mean that magnetic fields are bent by gravity, which I doubt they are... or at least much... others consider it to be a layer of the universe, kind of like another dimensional layer where we see a projection in 3 space of the effects of the bending of that layer by means of charge. Another question is how does the electron know to be attracted to the proton, if we imagine particles going out, we would expect everything to be repulsive to one another, so, this is another thing that is just referred to as a Feild. In short, no one really knows, or at least no one has proven a theory (as far as I know ) on what these effects actually are, so stay thinking on it!!!
The magnetic field is actually the same as the electric field, is just boosted into another reverence frame (Veritasium has a very nice video on that). But both are compounds of the electromagnetic force, which is based on the exchange of photons. So the particles of the magnetic field are photons.
Good stuff! Cool stuff to know. I've been subscribed to your channel for about a year now and I'm impressed that you haven't blown up your neighborhood hood yet. LOL!
Ahhh fuck. I did this almost exact same experiment in college as a project a bit before I dropped out. I remember crying on the floor a night before it was due with my experiment not working. I got it to work tho 😎 and got to present a little poster about it. God I miss school so so much 🥲
could you theoretically calculate the potential difference of an emitted photon from the LED by only knowing the y and x distances between each bright and the work function (constant for almost every LED)?
When i am in school... Kind of think similar... But lack of instruments... Couldn't able to do all types of cool experiments.... Glad someone did that...
The activation voltage is often referred to as the forward voltage in the LED industry. Noted as Of (little f). I've also measured lasers in a spectroradiometer and the noted wavelength is usually off; at least on the cheap lasers I've bought and measured. Thanks for putting these videos together!
I more mean to say the voltage potential required to give energy for the work function and a single photon, which your right is not exactly equal to voltage drop, but it should be fairly close to it nonetheless, for instance, a standard voltage drop on a blue led is between 2v and 3.3 volts depending on the material inside, so, this is the voltage drop across the led required for a photon to be emitted. Perhaps it would be better to call it the activation potential required
I’m not quite certain what you mean, although E=γmc^2 + pc, since a photon is treated as massless, the mc^2 part is 0, however, it does still have a momentum component due to symmetry, so we have E=pc, and p=h*f/c , so E= h*f/c *c = hf = hc/λ . And that is what we used. Although perhaps I am misunderstanding your comment, did this help in any way?
Hope you came back soon you're always so good at explaining what is happening and teaching us all how these things work
It pains me that this hasn't been watched more. This channel should have millions of subscribers but people would rather watch BS celebrity gossip.
Wyrmnacht true however you have to post more than 1 video every so many months.
Maybe you should learn about the socially vilified "Bell Curve" a bit.
mox plonk
I knew this nigga aint dead. One of the best maker channels in yt
This is pretty much what I'm learning in college, good video
this life hack will make it SO much easier to watch Nates videos.
watch them at 0.75 speed.
Holy crap - you're right. But... it makes him sound slightly drunk... XD
This is really awesome, I personally love these kind of videos and would love to see more. Also, do you think you could make a cathode ray tube?
Very fascinating video!! I think it needs more of Nate's face though ;)
Teach us how to build a good quality Geiger Counter. That's something I haven't seen on RUclips. At least not one of presentable quality.
Nate! If you liked my 3D printed Radio, then you might like my new 3D printed Magnetic Levitator! :)

Well I mean if ya arrest to the value of LEDs in this undertaking
Do you happen to watch thought emporium? They did a similar video and I think you two would get along.. colab maybe?
I’m not sure who that is, what is their full channel name? I would love to check them out! :D

Amazing. ..man ..i will try this experiment after my exams
Great to hear!! Good luck :)
But anyway good video! Great stuff! Amazing channel!
Planck's constant tells us how much energy a single photon will have, given a light wave of a certain frequency

Who's watching this in 2022?
Me...
I'm watching it in 420 man lol
Oh the pains of recording dim diffraction patterns #relatable.
Its been 4 months, why not uploading anymore ?
Cmon college ain't that hard, don't stop making videos.
Hope to see a new video soon.
:)
I know, college really isn’t that hard, I just need to get out there and do some more 😅 thank you :)
Love your channel keep a good work😀
hey what is the name of the calculator with graph that you used ????? plzz reply
Doesn't the graph imply that a 0 eV energy photon still has some wavelength? I think that fit really has to be forced through (0,0) for it to make sense.
Never ever close this channel or remove videos ...my whole life depends on it
May we see a video regarding the manipulation of plasma with electromagnetic fields in the future? I'm looking for information, and can't find a whole lot of it.
Who also needed to watch twice because you didn't get it.😓
i used plank's constant with every iteration of me watching this video.
Missing your videos!
Can u make a best project for exception . on 0 PCB (with or without microcontroller )
Keep it up bro. I love you videos.
Amazing!!!!😃

i dont think so, tim.
Nice video
Great video and explanations! Thanks for that interesting excourse into Physics :)
Good stuff! Cool stuff to know. I've been subscribed to your channel for about a year now and I'm impressed that you haven't blown up your neighborhood hood yet. LOL!

Initally you wrote .0839 but then changed it to .0834. Great video though.
This is amazing! Keep filming (=
One presented this well.
I'm always playing with the slow his voice speed down. For the microwave gun video he did years ago he's worth this range of presentations.
Yay quanta!
Hey can you (pulse) a Jacobs ladder with a disposable camera Circuit ??
This is amazing :D can you do the young's double slit experiment?
Could you please explain about the different natures of light like wave nature, particle nature, etc
When is your fussionreactor with cody’slab finished?
I have a question. How do I write to you. I've tried and tried but can't find your P.O box address.
I’m wondering how I could wirelessly activate 2 or more servos.
excelente
?
Keystone science why dose my microwave transformer dose not hmm pls help I have no idea
Make a video on joule thief circuit
why the heck is he using a dip pen? is he secretly from the 1900s?
could you theoretically calculate the potential difference of an emitted photon from the LED by only knowing the y and x distances between each bright and the work function (constant for almost every LED)?
Yep!
When i am in school... Kind of think similar... But lack of instruments... Couldn't able to do all types of cool experiments.... Glad someone did that...
What happened to you ! Why you are not making amazing video.
good one !
Could you please make a video on how to make a burning laser out of an old dvd drive
Why is he not uploading more videos ? :(
Can you maka a tutorial about how to make a kirlian ptotography please
He is wasted for 2 monts
Nice
Yeah probably
Like I want to measure for 16/4
How do make Plasma battery and what is Plasma in detail Plss
This is tough to watch I have a fear of lambdas.
@7:33 Why didn't you use the diode test mode in your multimeter?
Why was inverse tangent used for the angle calculation? Shouldn't the inverse tangent also be adjacent over opposite?
Haha, yess.... sometimes when I am filming I just do what comes to my head first, and that was not to use Pythagorean :P
Your mustache is flashy, though! lol
Ultraviolet catastrophy truely is a catastrophy
Yeet
It's been a while man, missed you 😭
who else watching this video in 2100

Will we be seeing any more of you in the future?
Nate, these videos make me feel so clueless
When is the bigger Tesla coil coming ?
Nate, I wasn't tantalized I was titillated ;)
How to make homemade microphone ?????
Your videos are accessible without being dumbed down. Excellent stuff!
I hated the quantum physics class I had to attend at college, but this is very cool! Nice work!
Lost track of you. I come back and you are talking more slowly now. FASTER FASTER FASTER! :p
But soooo many people complained
Electromagnetic spectrum
Cool! Non-flashy videos are also pretty cool
Awesome video Keystone!
Great video bosss
Is it 0.0839 or 0.0834? Hmm...
I miss my weekly videos 😭. I also look forward to watching your future videos dude! Keep it up!
Thank you! I’m sorry it’s been so long :/ I’m working on one this weekend finally
@@KeystoneScience Well im looking forward to that!
fucking amazing as always
Nice mustache. 🔥🔥😉

video an a tesla coil please!
Notification squad yasss
Awesome! Also are you still planning on using your vacuum pump for x-rays and high voltage?
Yep! That will be next week’s video! ( or at least first plasma fields )
Awesome! Can't wait!
Where did you go keystone? No vids in 4 months?
I know :/ I am making one tomorrow, I swear.
or could’ve you just used substituted Energy for mass times speed of light squared for simplicity
I’m not quite certain what you mean, although E=γmc^2 + pc, since a photon is treated as massless, the mc^2 part is 0, however, it does still have a momentum component due to symmetry, so we have E=pc, and p=h*f/c , so E= h*f/c *c = hf = hc/λ .

yeah that does I understood why you did the Young’s Double Slit I just got a little confused on the LED experiment
Another question: would you be able to replicate the Rutherford Gold Foil experiment?
Yeah science!!!!
ty!
