Vedclass · Answer

(C) In the photoelectric effect,the photoelectric current is directly proportional to the intensity of the incident light,provided the frequency is above the threshold frequency. Since the frequency and accelerating potential are kept constant,increasing the intensity of the incident light increases the number of photons incident per unit time,which in turn increases the number of photoelectrons emitted per unit time. Therefore,the photoelectric current increases.

In a photoelectric experiment,keeping the frequency of incident radiation and the accelerating potential fixed,if the intensity of incident light is increased,then:
