Quizplus · Accepted Answer

The maximum shift in wavelength in Compton scattering is given by the Compton wavelength, which is h/mc, where h is Planck's constant, m is the mass of the electron, and c is the speed of light. Substituting numerical values gives a Compton wavelength of about 2.43 × 10^-12 m. The maximum shift in wavelength occurs when the incident photon is scattered at an angle of 180 degrees (backscattered), and is given by twice the Compton wavelength, or about 4.86 × 10^-12 m. Therefore, the maximum shift in wavelength is 2 times the Compton wavelength or choice C.
