Particle Physics (25 of 41) What is a Photon? 9. Compton Scattering

In this video I will explain Compton scattering of a photon colliding with an electron and proton.

Next video in the Particle Physics series can be seen at:

I'm getting tired of saying how good are your lectures

[jeffreyluciana]

Excellent. Excellent. Thoroughly enjoyable

The proton mass is much larger than that of the electron, so the latter easily vibrate with the E-field of the photon and gain larger energy than the proton does

1 photon is one single sinusoide(one λ of both E and H), my deduction. I read everywhere E=hυ is energy for One Single photon. And in the right side υ is some number of [cycle/s], so E(1photon) is J.cycle. More explanatory in the equivalent formula E=hc/λ, where the wavelength(λ) is m/1cycle. Like this half of quantum energy must be in the "positive" half of the H and B sinusoidal fields, and half in the "negative" (but respecting E much bigger than H, by Free space impedance (wikipedia) E=377H). The total power of this is the Poynting vector S=EH in W/m^2 == J/sm^2.

The video is excellent, great information pace, no time to get board. Q. In the future, WHEN we can measure the mass of a photon, Einsteins equations will have to be modified? Is anyone publishing in this direction that I can read?

Then, if we find out a wave of lıght length smaller than visible lıght photon vibratıon length, we strıkes or collıdes it to electron partıcle dırectly.And then what happens to material atoms ?

Why are you using the symbol for the lambda particle when we are talking about photons? I understand we are using wavelengths but still
