Problem

Which of the following changes to a Compton-scattering experiment will most directly result in a larger increase in the photon’s wavelength after the collision? (a) Using an incident photon with half the original wavelength at the same scattering angle (b) Replacing the electron target with a proton of much greater mass (c) Increasing the scattering angle from 30∘30^{\circ} to 120∘120^{\circ} while keeping all other factors unchanged (d) Reducing the value of the speed of light used in calculations from 3.00×108 m s−13.00\times10^{8}\,\text{m}\,\text{s}^{-1} to 2.90×108 m s−12.90\times10^{8}\,\text{m}\,\text{s}^{-1}
