A beam of photons having energy for each photon equivalent to 24.8 keV is scattered through electrons primarily at rest. A photon in the beam is scattered in a direction which forms an angle of 30 degree with the incident beam.
(i) Determine the wavelength of the incoming photon?
(ii) Determine the change in wavelength of the incoming photon?
(iii) Determine the kinetic energy of the scattered electron?
