A photon of joule is absorbed by a material under special circumstances. The correct statement is

Electrons of the atom of absorbed material will go the higher energy states

Electron and positron pair will be created

Only positron will be produced

Photoelectric effect will occur and electron will be produced

Text Solution

Verified by Experts

The correct answer is:

For electron and positron pair production, minimum energy is 1.02 MeV.

Energy of photon is given

Since energy of photon is greater than 1.02 MeV. So, electron positron pair will be created.
