In the Compton effect, a 0.146 nm photon strikes a
free electron in a head-on collision and knocks it into the forward
direction. The rebounding photon recoils directly backward.
A - Use conservation of (relativistic) energy and momentum to
determine the kinetic energy of the electron. Use the
equation p= .
K=? eV
B - Determine the wavelength of the recoiling photon
= ?
nm
