In a photo electric experiment, if both the intensity and frequency of the incident light are doubled, then the saturation photoelectric current

Options

  1. Ais halved
  2. Bis doubled
  3. Cbecomes four times
  4. Dremains constant

Correct answer

B. is doubled

Step-by-step solution

In photoelectric effect, saturation photocurrent is directly proportional to the intensity of incident radiation but independent of frequency of incident radiation. Hence, saturation current in photoelectric effect becomes double when both intensity and frequency of the incident light are doubled.
