MHT CET 2024 Physics question

In photoelectric effect, the photocurrent

(1)decreases with increase in frequency of incident photon
(2)increases with increase in frequency of incident photon
(3)does not depend on the frequency of photon but depends only on the intensity of incident lightCorrect
(4)depends both on intensity and frequency of incident radiation

Answer: (3)

Solution

The photocurrent is the number of photoelectrons emitted per second that reach the anode. For radiation whose frequency is above the threshold frequency, the number of photoelectrons emitted per second is proportional to the number of photons incident per second, i.e. to the intensity of light. The frequency
