The experimental observation(s) below that require(s) a quantum explanation for the photoelectric effect
 a. is that more photoelectrons are emitted when the light frequency increases.
  b. is that the maximum kinetic energy of the photoelectrons is related linearly to the frequency of the light.
  c. is that every metal surface has a work function, a minimum amount of energy needed to free electrons.
  d. is that the stopping potential measures the kinetic energy of the photoelectrons.
  e. are all of the above.

Question 2

Photoelectrons are ejected when monochromatic light shines on a freshly-prepared (oxide-free) sodium surface. In order to obtain the maximum increase in the number of electrons ejected per second, the experimenter needs to
 a. increase the frequency of the light.
  b. increase the intensity of the light.
  c. increase the area illuminated by the light.
  d. do all of the above. e. do only (b) and (c) above.
