Zeeman Effect

Zeeman Effect

Model No: AGN-1902
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 level sand the spectral lines are also split. This splitting is called the Zeeman Effect. It consists of following instruments: –
  1. Constant Deviation Spectrograph as per Cat. No. 1885
