Question

What is meant by pair production and pair annihilation.....

Answer 1

ANSWER___(◠‿◕)

Pair Production:

________________

In physics, formation or materialization of two electrons, one negative and other positive (proton), from a pulse of electromagnetic energy travelling through Matter, usually in the vicinity of an atomic nucleus.
Pair Production is a direct conversion of radiant energy to matter.

Pair Annihilation:

_________________

Pair Annihilation means the reverse process of pair production. In the pair annihilation, the electron and proton in the stationary state combine with each other and annihilation. Surely, the particles are disappeared and radiation energy will occur instead of two particles.

Hey mate ☺️

$\huge \red {Ur Answer}$

The conversion of a photon into an electron-positron pair on its interaction with the strong electric field surrounding a nucleus is called pair production. The converse of pair production in which an electron and positron combine to produce two photons is known as annihilation of matter.
