A)greater than or equal to the initial wavelength.
B)equal to the initial wavelength.
C)less than or equal to the initial wavelength.
D)greater than the initial wavelength.
E)less or greater depending on the scattering angle.

Question

Quizplus · Accepted Answer

In Compton scattering, the wavelength of the scattered photon is always greater than the initial wavelength when the scattering angle is greater than $0^\circ$. This is due to the transfer of energy from the photon to the electron, resulting in an increase in wavelength.
