In photoelectric effect, the photocurrent

  • A
    decreases with increase in frequency of incident photon.
  • B
    increases with increase in frequency of incident photon.
  • Correct answer
    C
    does not depend on the frequency of photon but depends only on the intensity of incident light.
  • D
    depends both on intensity and frequency of incident radiation.

Solution

Photocurrent is independent of the frequency of photon. However when intensity of incident photon increases number of electrons emitted from the surface also increases, thereby increasing photocurrent.

Hence, the correct answer is option: 'C'.
