Vedclass · Answer

(D) According to Einstein's photoelectric equation,$K_{max} = h
u - \Phi$,where $h
u$ is the energy of the incident photon and $\Phi$ is the work function of the metal surface.The kinetic energy of photoelectrons depends only on the frequency of the incident radiation $(
u)$ and the work function of the material $(\Phi)$.Intensity of incident radiation affects the number of photoelectrons emitted per unit time (photoelectric current),but it does not affect the kinetic energy of individual photoelectrons.Therefore,both Statement-$I$ and Statement-$II$ are incorrect.
