What do you call the effect of splitting a spectral line into several components in the presence of a static magnetic field?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. Zeeman effect.

  • The Zeeman Effect is a physics and astronomy phenomenon that involves the splitting of a spectral line into two or more components with slightly differing frequencies when the light source is put in a magnetic field.
  • It is named after Pieter Zeeman, a Dutch physicist.
  • Because of the magnetic field, the electron orbitals are distorted, causing the effect.
  • This phenomenon is extremely beneficial for determining an electron's charge/mass ratio and magnetic moment.
