Question

Quizplus · Accepted Answer

When a photon is scattered from an electron, it undergoes what is known as Compton scattering, which results in an increase in the photon's wavelength. This is because some of the photon's energy is transferred to the electron, leading to a decrease in the photon's energy and, according to the relationship $E = \frac{hc}{\lambda}$ (where $E$ is energy, $h$ is Planck's constant, $c$ is the speed of light, and $\lambda$ is wavelength), an increase in its wavelength.
