In photoelectric effect, the photocurrent

Options

  1. Adecreases with increase in frequency of incident photon.
  2. Bincreases with increase in frequency of incident photon.
  3. Cdoes not depend on the frequency of photon but depends only on the intensity of incident light.
  4. Ddepends both on intensity and frequency of incident radiation.

Correct answer

C. does not depend on the frequency of photon but depends only on the intensity of incident light.

Step-by-step 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.
