Question

4. Explain the splitting of spectral lines in Normal Zeeman Effect for the 2p to 1s transition.

Answer 1

Answer:

Explanation:

The atomic energy levels, the transitions between these levels, and the associated spectral lines discussed to this point have implicitly assumed that there are no magnetic fields influencing the atom. If there are magnetic fields present, the atomic energy levels are split into a larger number of levels and the spectral lines are also split. This splitting is called the Zeeman Effect.

ZEEMAN EFFECT

The pattern and amount of splitting are a signature that a magnetic field is present, and of its strength. The splitting is associated with what is called the orbital angular momentum quantum number L of the atomic level. This quantum number can take non-negative integer values. The number of split levels in the magnetic field is 2 * L + 1. The following figure illustrates the Zeeman effect.
