Give a brief account of
a. [5 marks] Rayleigh scattering,
b.[5 marks] the photoelectric effect,
c. [5 marks] the Compton effect and
d. [5 marks] pair/triplet production.
For each of them, describe the phenomenon, account for it in terms of physical principles, and state the photon energy range and atomic number Z of target material over which it is important.

Which of the following statements are true for the photoelectric effect? Give all the correct answers, e.g., enter ABC. The maximum kinetic energy of the ejected electrons is proportional to the velocity of the incoming photons. The maximum kinetic energy of the ejected electrons increases linearly with the frequency of the incident light. The frequency of the incoming photons must be larger than a certain minimum value in order to eject electrons from the metal. The maximum kinetic energy of...
