(kŏmp′tən), Arthur Holly 1892-1962.
American physicist who proved Albert Einstein's statement that a particle of light has momentum even though it has no mass. Compton's experiments showed that when particles of light (called photons) collide with other particles, such as electrons, they lose energy and momentum and the light's wavelength increases. This phenomenon became known as the Compton effect.
