In photoelectric effect, the photo current

Options

  1. Aincreases with increase of frequency of incident photon
  2. Bdecreases with increase of frequency of incident photon
  3. Cdoes not depend on the frequency of photon but depends only on intensity of is cident light
  4. Ddepends both on intensit, and frequency of incident beam

Correct answer

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

Step-by-step solution

When intensity of incident photon increases number of electrons emitted from the surface increases. Thus current increases. It is independent of frequency of photon.
