The reverse process of X ray production can be related to:
Correct answer: B. Photoelectric effect
- A. Compton effect
- B. Photoelectric effect
- C. Pair production
- D. Pair Annihilation
Explanation
Pair production is the process in which a photon interacts with a nucleus and produces an electron-positron pair. This is the reverse of the annihilation process, where an electron and a positron collide and annihilate, producing two photons (often in the form of gamma rays). Therefore, option c is correct.

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.
