Compton effect
noun Physics.
the increase in wavelength of monochromatic, electromagnetic radiation, as a beam of photons or x-rays, when it is scattered by particles whose size is small compared to the wavelength of the radiation.
Origin of Compton effect
First recorded in 1920–25; named after A. H. Compton

Scientific definitions for compton effect
Compton effect
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.
