The X-rays consist of:
Correct answer: D. High-energy photons
- A. high-energy proton
- B. High-energy electrons
- C. High-energy -rays
- D. High-energy photons
Explanation
X-rays are a form of electromagnetic radiation similar to visible light. Unlike light, however, x-rays have higher energy and can pass through most objects, including the body. Medical x-rays are used to generate images of tissues and structures inside the body. Hence, X-rays consist of photons, not particles.

About Photons and the Particle Model of Light
The particle model treats light as photons with energy E equals hf and momentum related to wavelength. Questions involve the photoelectric effect, work function, threshold frequency, stopping potential and photon energy, while distinguishing particle behaviour from the wave description of interference and diffraction.
