X-rays travel as bundles of energy called

• A. Protons
• B. Phasers
• C. Particles
• D. Photons

Answer: (D)

X-rays are a form of electromagnetic radiation, and their energy is carried in discrete packets called photons. Each photon is a quantum of energy set by its frequency (E = hf), so the radiation travels as bundles of energy rather than as a continuous, undivided stream. This photon description explains how X-rays interact with matter—absorption or scattering occurs when individual photons are involved. Protons are massive particles, not energy bundles. The term “phasers” isn’t a physics term for X-ray energy. “Particles” is too vague and does not specify the energy-carrying quanta that define X-rays. Therefore, the correct concept is photons.
