Vedclass · Answer

(C) In the photoelectric effect,the photoelectric current $(I)$ is directly proportional to the number of photoelectrons emitted per unit time.This number of emitted photoelectrons is directly proportional to the number of incident photons per unit time (intensity of light).Since the intensity of the light is kept constant,the number of incident photons per unit time remains unchanged.Although the frequency of the light is doubled,which increases the kinetic energy of the emitted photoelectrons,it does not change the number of photons incident on the surface.Therefore,the number of photoelectrons emitted per unit time remains constant,and the photoelectric current remains the same.

Monochromatic light with a frequency well above the cutoff frequency is incident on the emitter in a photoelectric effect apparatus. The frequency of the light is then doubled while the intensity is kept constant. How does this affect the photoelectric current?
