The reverse process of photo electric effect is
Correct answer: C. Production of X-rays
- A. Annihilation of matter
- B. Pair production
- C. Production of X-rays
- D. Nuclear fission
Explanation
The reverse process of the photoelectric effect is b) pair production. The photoelectric effect involves the emission of electrons from a material when it absorbs photons, while pair production is the creation of particle-antiparticle pairs from high-energy photons.

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.
