The reverse process of pair production is known as:
Correct answer: A. Annihilation of matter
- A. Annihilation of matter
- B. Anti-pair production
- C. Materialization of matter
- D. Annihilation of practical into its anti-particle
Explanation
When a particle and its antiparticle collide, they annihilate each other, converting their mass into energy according to Einstein's famous equation E=mc2. This process is known as the annihilation of matter and it is the reverse of pair production.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
