Arthur Compton

Arthur Compton (1892–1962) was an American experimental physicist best known for his work in the field of X-ray and gamma-ray physics. He is most renowned for the discovery of the Compton effect, which demonstrates the particle nature of electromagnetic radiation. This effect describes how X-rays or gamma rays collide with electrons, resulting in a change in the wavelength of the radiation, which provides evidence for the dual wave-particle nature of light.
