Vedclass · Answer

(D) The photoelectric effect is related to the incident light frequency $(v)$ by the following equation:$E_k = hv - \phi$where $\phi$ is the work function of the material and $E_k$ is the kinetic energy of the photoelectron.Since the electrons are emitted from different depths within the metal,they lose varying amounts of energy due to collisions before escaping the surface.Therefore,the kinetic energy of emitted photoelectrons ranges from $0$ to a maximum value $(E_{k,max} = hv - \phi)$.Consequently,the speed of the photoelectrons ranges from zero to a maximum value.
