Question

The splitting of spectral lines in the presence of a magnetic field is known as _____ effect.

Answer 1

1. Zeeman effect: It was observed that when the atom emitting radiations are placed in a strong magnetic field, each spectral line is split into a number of lines. This phenomenon is called the Zeeman effect.

Hence, the splitting of spectral lines in the presence of a magnetic field is known as the Zeeman effect.
