In the Compton effect, a 0.128 nm photon strikes a free electron in a head-on collision and knocks it into the forward direction. The rebounding photon recoils directly backward.

Part A

Use conservation of (relativistic) energy and momentum to determine the kinetic energy of the electron. Use the equation p=Ec=hfc=h?. K = eV

Part B

Part complete

Determine the wavelength of the recoiling photon.

?? = 0.133 nm
