Definition of terms |
λc = Compton wavelength, h = Planck's constant, m = mass of particle, c = speed of light |

Comments |
When a photon of wavelength λ collides with a stationary particle, it will recoil at an angle q with a new wavelength λc'.
The Compton effect equation states that in this case
λ' − λ= λc(1 − conθ) where
λ
C
=
h
m
c
is called the Compton wavelength of the particle.
The Compton wavelength is also the length scale at which the effects of relativity become important |
