The Compton effect is the name given for the scattering of light by free or nearly free electrons.[1] Arthur Holly Compton (1892-1962) discovered that when a photon strikes an electron, it imparts both energy and momentum to the electron, which recoils. After collision, the photon’s energy has decreased and therefore its wavelength has increased. The effect is considered the confirmation that light is made of particles and photons have momentum. Compton measured photon-electron scattering in 1922 and received the Nobel in Physics in 1927 for his achievement in contributing to the theory of wave-particle duality.[2][3][4]
