Problem: An x-ray photon scatters from a free electron at the rest at an angle of 160 degrees relative to the incident direction.
Part A: If the scattered photon has a wavelength of 0.310 nm, what is the wavelength of the incident photon?
_______ nm
Part B: Determine the energy of the incident and scattered photons.
______ keV (incident)
______ keV (scattered)
Part C: Find the kinetic energy of the recoil electron.
______ eV
