Give examples of production of -(i) photons from electrons (ii) electrons from photons.

Text Solution

Verified by Experts

(i) When high velocity electrons (cathode rays) strike the surface of hard metals like tungste, platinum, etc, X-rays are produced.
(ii) When a light of suitable frequency or any other electromagnetic radiation strikes a metal surface, electrons are ejected from it.
