Does not depend on the frequency of the photon.

Vedclass · Answer

(C) In the photoelectric effect,the number of photoelectrons emitted per unit time is directly proportional to the intensity of the incident radiation,provided the frequency is above the threshold frequency. Since the photocurrent is directly proportional to the number of emitted photoelectrons,it depends on the intensity of the incident light. The frequency of the incident photon determines the maximum kinetic energy of the emitted photoelectrons,but it does not affect the magnitude of the photocurrent. Therefore,the photocurrent is independent of the frequency of the incident photon.
