Compton scattering occurs with what type of photons?

• A. Low-energy photons
• B. Very-high-energy photons
• C. Moderate to high-energy photons
• D. Gamma photons only

Answer: (C)

Compton scattering is the inelastic interaction where a photon collides with an electron and transfers part of its energy, changing the photon's wavelength. This effect is most noticeable for photons that have enough energy to cause an inelastic collision with electrons—typical of moderate to high-energy photons. At very low energies, elastic Rayleigh scattering and photoelectric absorption dominate, so Compton scattering isn’t the main process. At extremely high energies, other interactions like pair production become more significant, so Compton scattering isn’t the sole outcome. In diagnostic radiography, X-ray photons in the tens to hundreds of keV range show Compton scattering prominently, which aligns with the description of moderate to high-energy photons.
