A)0 $\circ$
B)90 $\circ$
C)180 $\circ$
D)There is no maximum value for the increase in wavelength.
E)The wavelength of the x-ray photons doesn't increase.It decreases.

Quizplus · Accepted Answer

The maximum possible increase in the wavelength of the photons during Compton scattering occurs when the scattering angle is 180 degrees, meaning the photons are scattered directly backward.
