Vedclass · Answer

(C) The photoelectric current is directly proportional to the intensity of the incident light (illumination). According to the photoelectric effect,when light of a suitable frequency falls on a metal surface,electrons are emitted. The number of photoelectrons emitted per second is directly proportional to the intensity of the incident radiation. Therefore,a change in the intensity of illumination results in a corresponding change in the photoelectric current.
