The reverse process of Photoelectric effect is:
Correct answer: D. X-rays production
- A. Compton Effect
- B. Annihilation
- C. Pair-production
- D. X-rays production
Explanation
In photoelectric effect the electrons are emitted from the metal surface when it is exposed to light, while in production of X-rays when fast moving, electron strike the metal surface electromagnetic waves are produced.

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.
