In 1905, Einstein published his paper on the Photoelectric Effect, one of four papers he published in his 'miracle' year. One of the implications was that light, a form of electromagnetic radiation, behaved as particles. This suggested that particles of light (named quanta by Einstein, but later named as photons) had momentum.
What was missing was experimental verification.

The Compton scattering experiment aimed to show that light does have momentum.
The Compton Effect is the effect of photons of rays scattering electrons, and provided evidence for the particle nature of light. This video covers an explanation and the mathematical relationship that Arthur Compton derived by assuming a quantum nature and conservations laws. |

Compton's scattering Formula looks at the relationship between xray photons wavelengths and the angle of interaction with electrons. How is it derived?
