Question

In the photoelectric effect, light strikes a metal and photoelectrons are ejected.

(a) If the intensity of the light is increased, while the frequency is kept constant, the maximum kinetic energy of the photoelectrons will _____ (increase, decrease, stay the same) while the rate of photoelectrons will ______ (increase, decrease, stay the same).
(b) If the frequency of the light is increased, while the intensity is kept constant, the maximum kinetic energy of the photoelectrons will______ (increase, decrease, stay the same), while the rate of photons onto the metal will _______ (increase, decrease, stay the same), so the rate of photoelectrons will _______ (increase, decrease, stay the same).
