Q. In the Compton Effect, momentum conservation applies so total momentum of the photon and the electron is the same before and after the scattering occurs. Assume that the incident photon moves in the +x direction and scattered photon emerges at an angle of θ = 90°, which is in the -y direction. The incident photon has a wavelength of 9 x 10-12 m. Find out the x and y components of the momentum of the scattered electron.
