Compton Effect, Compton Shift, and Modified & Unmodified Radiation

Compton Effect -The Compton Effect is a phenomenon in which X-rays or gamma rays scatter off electrons, resulting in a change in wavelength. When a high-energy photon collides with an electron, it transfers part of its energy to the electron. The electron recoils and the photon emerges with reduced energy and increased wavelength. Compton Shift

The Compton Shift is the difference between the initial and final wavelength of the
