Vedclass · Answer

(D) The photoelectric current is directly proportional to the intensity of the incident light,provided the incident frequency is greater than the threshold frequency.Since the saturation current depends only on the number of photoelectrons emitted per second,which is directly proportional to the intensity of the incident light,doubling the intensity will double the saturation current.The frequency of the incident light affects the kinetic energy of the emitted photoelectrons,not the number of photoelectrons (saturation current),as long as it remains above the threshold frequency.Therefore,when the intensity is doubled,the photoelectric saturation current doubles.

Light of a certain frequency and intensity incident on a photosensitive material causes the photoelectric effect. If both the frequency and intensity are doubled,the photoelectric saturation current becomes
