The photoelectric effect is a phenomenon in which electrons are emitted from the surface of a metal when it is exposed to light of sufficient frequency. This effect demonstrates that light can transfer energy in discrete packets called photons. When a photon strikes the metal surface, its energy is absorbed by an electron. If the energy of the photon exceeds the work function of the metal, which is the minimum energy required to release an electron from the surface, the electron is ejected. The kinetic energy of the emitted electron depends on the energy of the incident
