Solve the following problem given below:
Problem: An incident x-ray photon is scattered from a free electron that is initially at rest. The photon is scattered straight back at an angle of 180? from its initial direction. The wavelength of the scattered photon is 8.60 x 102 nm.
Part I: What is the wavelength of the incident photon?
Part II: What is the magnitude of the momentum of the electron after the collision?
Part III: What is the kinetic energy of the electron after the collision?
Please use as much detail as possible in solution.
