Of the following statement about the photoelectric effect, which are true and which are false?
(a) The greater the frequency of the incident light is, the greater is the stopping potential.
(b) The greater the intensity of the incident light is, the greater is the cutoff frequency.
(c) The greater the work function of the target material is, the greater is the stopping potential.
(d) The greater the work function of the target material is, the greater is the cutoff frequency.
(e) The greater the frequency of the incident light is, the greater is the maximum kinetic energy of the ejected electrons.
(f) The greater the energy of the photons is, the smaller is the stopping potential.
