Light of two different frequencies whose photons have energies of 2 eV and 5.0 eV are incident one by one on a metal surface of work function 1.5 eV. The ratio of maximum energies of emitted electrons will be Ultraviolet beam of wavelength 280 nm is incident on lithium surface of work function 2.5 eV. [...]

When light of frequency v1 is incident on a metal with work function W (where hv1 > W), the photocurrent falls to zero at a stopping potential of V1. If the frequency of light is increased to v2, the stopping potential changes to V2. Therefore, the charge of an electron is given by the charge [...]
