The Compton Effect

According to Einstein's theory about the photoelectric effect, light consists of quanta with definite energies corresponding to certain frequencies. The light quantum is called a photon. When Arthur Compton in 1922 sent X-ray photons against a metal surface, the scattered photons had a longer wavelength because part of the incident photon energy was transferred to an electron. The experiment confirmed that electromagnetic radiation could also be described as photon-particles following the laws of mechanics.
