MHT CET 2026 Physics question

In photoelectric effect, keeping the frequency of incident radiation and accelerating potential fixed, if the intensity of incident light is increased,

(A)the photoelectric current increases.Correct
(B)the kinetic energy of emitted photoelectrons increases.
(C)photoelectric current decreases.
(D)kinetic energy of emitted photoelectrons decreases.

Answer: (A)

Solution

The photoelectric current is proportional to the number of photoelectrons emitted per second, which is proportional to the number of incident photons per second, i.e. to the intensity of light (for fixed frequency above threshold and fixed accelerating potential). So increasing the
