Compton Scattering is a quantum physics phenomenon where photons collide with electrons, leading to energy and wavelength changes. Discovered by Arthur Holly Compton, it provides evidence for light's particle nature and is described by the Compton equation. This effect is crucial in understanding light-matter interactions and has applications in astrophysics, such as the Sunyaev-Zel'dovich effect and gamma-ray production.
