When light of sufficiently low wavelength fall on a metal surface, electrons are ejected. This phenomenon is called the photoelectric effect and can be understood in terms of the particle nature of light. i.e. if$\nu$is the frequency light that falls on metallic surface, which eject an electron, then we can say that$E=h\nu$quanta of energy is absorbed during photoelectric emission.
