Short wavelength X-rays correspond to which energy level?

Short wavelength X-rays correspond to which energy level?

• A. Higher energy
• B. Lower energy
• C. Neutral energy
• D. No energy

Answer: (A)

Photon energy increases as wavelength decreases. The energy of a photon is E = h c / λ, so shorter wavelengths give higher energy per photon. X-rays have very short wavelengths, meaning their photons carry a relatively large amount of energy. That’s why short wavelength X-rays correspond to higher energy. The ideas of neutral energy or no energy don’t apply here, and lower energy would come with longer wavelengths.
