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

Topic: JEE PYQ

Answer: A. Full step-by-step solution below.

  1. Ais doubled
  2. Bremains constant
  3. Cbecomes for times
  4. Dis halved

Correct answer: A

(a) The saturation photoelectric current is directly proportional to the intensity of incident radiation but it is independent of its frequency. Therefore, the saturation photoelectric current becomes doubled, when both intensity and frequency of the incident light are doubled.
Among the given options, option (a) is the most suitable.
