Problem
Light of frequency 2ν0 (where ν0 is the threshold frequency of a metal) produces photoelectrons from the metal. If the intensity of this light is reduced to one-fourth of its initial value, which statement is correct?
(a) Both Kmax and the saturation photocurrent become one-fourth
(b) The maximum kinetic energy remains the same, but the saturation photocurrent becomes one-fourth
(c) Both the maximum kinetic energy and the saturation photocurrent remain unchanged
(d) The maximum kinetic energy becomes one-fourth, while the saturation photocurrent remains unchanged
