Vedclass · Answer

(A) According to Einstein's photoelectric equation,a single incident photon ejects a single electron. When the intensity of light increases,the number of incident photons per unit area per unit time increases. Since each photon ejects one electron,the number of emitted photoelectrons increases,which leads to an increase in the photo-current. The maximum kinetic energy of emitted photoelectrons is given by $K_{\max} = h
u - \Phi$,where $h
u$ is the energy of the incident photon and $\Phi$ is the work function. Since the energy of individual photons does not change with intensity,the maximum kinetic energy of the emitted photoelectrons remains independent of the intensity of incident light.
