Vedclass · Answer

(C) According to Einstein's photoelectric equation,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 of the metal.Since some electrons lose energy due to collisions before escaping the surface,the actual kinetic energy $K$ of the emitted photoelectrons ranges from $0$ to $K_{max}$.Therefore,the kinetic energy of any emitted photoelectron is always less than or equal to the maximum kinetic energy $(K \le K_{max})$.
