IB Physics. Compton Effect

A tutorial sheet of questions on the Compton effect follows.

  1. Is momentum conserved in the scattering of an X-ray photon by a free electron?
  2. Is kinetic energy conserved in the scattering of an X-ray photon by a free electron?
  3. An photon of energy 20.0 keV is scattered through an angle of 90.0° when it is scattered by a free electron. Find the kinetic energy of the scattered electron.
