What is Compton scattering?

Compton scattering is a phenomenon in which a photon (a particle of light) collides with an electron, transferring some of its energy to the electron and causing it to recoil. This results in a change in the wavelength and energy of the photon, as well as a change in the direction of its propagation. Compton scattering is an important process in the field of quantum mechanics and is used in various applications, such as medical imaging and X-ray spectroscopy.
