A Compton scattering experiment is performed in which the scattered photons have a maximum energy of 17.2 keV.What was the incident energy of the photons used in this experiment?
A) 16.6 keV
B) 18.5 keV
C) 16.1 keV
D) 17.8 keV

Question

Quizplus · Accepted Answer

In Compton scattering, the maximum energy of the scattered photon occurs when the scattering angle is zero, meaning the incident and scattered photons have the same energy. Therefore, the incident energy must be equal to or greater than the maximum scattered energy, which is 17.2 keV. Among the options, 18.5 keV is the only energy greater than 17.2 keV.
