What is Compton Effect?
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. Arthur Compton studied this effect in the year 1922. During the study, Compton found that wavelength is not dependent on the intensity of incident radiation. It is dependent on the angle of scattering and on the wavelength of the incident beam.
Where,
Ө: the angle at which radiation scattered
m0: rest mass of an electron
h/m0c : Compton wavelength of the electron
λs and λ0: radiation spectrum peaks.
Difference Between Compton Effect and Photoelectric Effect
| Compton effect | Photoelectric effect |
| This is the effect caused by the inelastic scattering of high-energy photons that are bound to free electrons. | This is the effect caused by the weakly bound electrons that are ejected from the surface of the material when electromagnetic radiation interacts with the electrons. |
| Arthur Compton explained the effect. | Albert Einstein explained the effect. |
| The energy associated with the free electrons is mid-energy. | The energy associated with the electrons is low-energy. |
| The wavelength of the scattered photon is higher than that of the incident photon. | The wavelength is not observed as the photon disappears after interacting with the electrons. |
