Vedclass · Answer

(D) The photoelectric effect is related to the incident light frequency ($ 
u $) by the following Einstein's photoelectric equation:$E_{k} = h 
u - \phi$where $\phi$ is the work function of the material and $E_{k}$ is the kinetic energy of the photoelectron.Since the electrons inside the metal can lose energy due to collisions before escaping the surface, they emerge with a range of kinetic energies.Consequently, the photoelectrons emitted from the surface of sodium metal have speeds varying from zero to a certain maximum value, depending on the incident photon energy.

The photo-electrons emitted from a surface of sodium metal are such that
