Einstein Declares that Light is Particles (Photons)! Dang it, Man! | Doc Physics

But I thought light was a wave. It shows freakin' diffraction. Grrrr.

I have been surfing the internet for hours! trying to figure this stuff out but nope and suddenly i run across your videos and finally after hours i finally have a better understanding of this stuff not complete but a good enough one to let me sleep peacefully. Thank you very much :3

avg kinetic energy is lacking energy to come out as light

[jacobvandijk]

Can you help me, please? The vibration of the particles in the blackbody gives them some average temperature and thus some average energy. Given the number of particles there is some total energy and this is E = n . (h .f) . Is this right so far? If so, why then does the intensity drop off after some (high) level of f ??? And why does this explain the need for integer numbers (n)?

Thanks for posting these videos! They've helped immensely with Phys 211 and 212, and now 213! Also...do you need a care package of batteries for your calculator? You seem to be running low for long stretches! ;)

Style of speak let to luck of concentration

i got the peak point of wavelength but i still couldn't get why the wavelength decreases after peak.After pick it could stay steady but it starts to decrease.why? I can't find the respond.
Btw thanks for the video, it is pretty useful.

Yes, Einstein was quite insane and did not understand electromagnetic theory even though he plagiarized much of it in his relativity papers, often having the causal relations reversed.

I've never seen it before.
But I suggest you see some interesting videos on SALEH THEORY-com about behaviors of photon.

holy shit you lost me half way through
