The Compton effect is defined as the effect that is observed when x-rays or gamma rays are scattered on a material with an increase in wavelength.
Compton's effect is a very important effect as it demonstrates that light cannot be explained in a pure waveform.
The conventional theory of the electromagnetic wave cannot explain how the light of low intensity shifts its wavelength of the radiation should behave as a particle.
It is a phenomenon in which electrons collide and are dispersed as X rays.
The wavelength of the radiation which is dispersed doesn't depend on the rate of the radiation.
But it is dependent on the wavelength of the beam incident and the angle at which it is scattered.
Commonly the name Compton's effect is given to the collision of a photon with an electron.
