What is emission spectrum?

Text Solution

Verified by Experts

After the excitation of atom, electrons come down to lower energy levels and in the process they emit electromagnetic radiations. The energy of these electromagnetic radiations is exactly equal to the difference in the energy levels where the transition has occurred. For a given atom when these radiations are brought on a photographic plate, a number of radiations constitute to form Emission spectrum of atom. It is the characteristic of an atom.
