In photoelectric effect, the number of photo-electrons emitted is proportional to

Options

  1. Avelocity of incident beam
  2. Bfrequency of incident beam
  3. Cintensity of incident beam
  4. Dwork function for cathode material

Correct answer

C. intensity of incident beam

Step-by-step solution

By increasing the intensity of incident beam, the number of emitted photo-electrons can be increased. Hence, number of photo-electrons emitted is proportional to the intensity of the incident beam.
