When photon energies are as high as the electron rest energy of 511 keV, yet another process, the Compton scattering, may take place. Above twice this energy, at 1.022 MeV pair production is also more likely. Compton scattering and pair production are examples of two other competing mechanisms. Even if the photoelectric effect is the favoured reaction for a particular interaction of a single pho… WebParticle Nature of Light. The emission of free electrons from a metal surface when light is shone on it, is called photoemission or the photoelectric effect. This effect led to the conclusion that light is made up of packets or quantum of energy. Now the question was whether the light quantum theory was indicative of the particle nature of light.
