Scientific definitions for Compton effect

Compton effect

  1. An increase in the wavelength of electromagnetic radiation, especially of x-rays or gamma-rays, when the photons constituting the radiation collide with free electrons. As a result of the Compton effect, the photons transfer some of their energy to the electrons. It is mainly through the Compton effect that matter absorbs radiant energy.
