Question

Explain pair production and pair annihilation with
example.​

Answer 1

Pair production is the creation of an elementary particle and its antiparticle, for example creating an electron and positron, a muon and antimuon, or a proton and antiproton.conserved. There exists an inverse process to pair production called pair annihilation, in which a particle and its antiparticle collide and annihilate each other, the total energy of the two particles appearing as electromagnetic radiation.

Answer 2

$\huge\underline\mathfrak\purple{Your~Answer♥}$

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.

$\huge\boxed{More~to~know:}$$\huge{✍}$

$\bold\red{Pair~production}$

Pair production is the process that results in the conversion

of a photon into an electron–positron pair. Since photon has no rest mass, we can say that this process converts energy into mass according to Einstein's mass energy relation E = mc².

$\bold\pink{Pair~annihilation}$

There exists an inverse process to pair production called pair annihilation, in which a particle and its antiparticle collide and annihilate each other, the total energy of the two particles appearing as electromagnetic radiation.
