Compton scattering, discovered by American physicist Arthur Holly Compton, is the scattering of a photon by an electron. It results in a decrease in energy of an X-ray or gamma ray photon, called the Compton effect. In this article, we provide a simple, concise discussion about one of three principle forms of photon interaction "Compton scattering" which demonstrates the particle nature of electromagnetic radiation.
