An X-ray photon with wavelength 0.050nm and a γ-ray photon with wavelength 0.0050nm each scatter through an angle of 90∘ from free electrons. Which statement correctly compares the percentage energy lost by the two photons as a result of the scattering?
(a) Both photons lose the same percentage of their energy.
(b) Both photons lose less than 1% of their energy, so any difference is negligible.
(c) The γ-ray photon loses a greater percentage of its energy.
(d) The X-ray photon loses a greater percentage of its energy.
