A 3100 TeV photon strikes an electron at rest and scatters by anangle of 120°. Find the frequency of the reflected photon using 2.4pm for the Compton wavelength. Also find the kinetic energy of theelectron.
solve it using eV not  joule. Please show all the workwith all the steps. I want to learn how to slove this kind ofproblem because similar one will ibe n my final exam.
Thank you
