This problem, we're going to talk about compton scattering.
00:02
So remember that compton scattering happens when a photon, in this case, an x -ray photon, strikes an electron that's initially at rest.
00:14
And as a result, the photon loses part of its momentum and energy and transfers them to the electron.
00:25
So if we write conservation of energy here, we have that the energy of the photon, i'm sorry, is equal to the energy of the outgoing photon, i'm going to call it e gamma prime, plus the kinetic energy gained by the electron.
00:46
Now, using that the energy of a photon is hc over lambda, where lambda is the wavelength, we get that hc over lambda is the wavelength, we get that hc over lambda is equal.
00:57
To hc over on the prime plus the kinetic energy of the electric...
