A)greater than its initial value.
B)equal to its initial value.
C)less than its initial value.

Question

Quizplus · Accepted Answer

The collision described is an example of Compton scattering, where a photon collides with a stationary electron. In this process, the photon transfers some of its energy to the electron, resulting in an increase in the photon's wavelength (a decrease in energy). Thus, the wavelength of the photon after the collision is greater than its initial value.
