Q. In a photoelectric experiment, if both the intensity and frequency of the incident light are doubled, then the saturation photoelectric current
A) Remains constant
B) Is halved
C) Is doubled
D) Becomes four times
Explanation
(c) 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 double, when both intensity and frequency of the incident light are doubled
