Compton Scattering Calculator

Calculate the Compton wavelength shift and scattered wavelength of a photon from the scattering angle and incident wavelength

Frequently Asked Questions

Why does the shift not depend on the incident wavelength?

The Compton shift depends only on the scattering angle and the electron Compton wavelength. The incident wavelength sets the starting point but not the size of the shift itself.

What is the largest possible shift?

The maximum shift occurs at a full backscatter of 180 degrees and equals twice the electron Compton wavelength, about 4.85 picometers.

What does Compton scattering prove?

It shows that light carries momentum and behaves like particles, which was key evidence for the quantum description of electromagnetic radiation.
