Compton equation

Compton equation

[′käm·tən i‚kwā·zhən]
(quantum mechanics)
The equation for the change in wavelength Δλ of radiation scattered by electrons in the Compton effect, Δλ = λc (1 - cos θ), where λc is the Compton wavelength of the electron, and θ is the angle between the directions of incident and scattered radiation.
