Introduction

The Zeeman effect is the splitting of spectral lines of atoms when they are placed in a magnetic field. It exhibits space quantization and is one of the few fundamental atomic physics experiments which can be performed in a teaching laboratory.

Description of the Experimental Set-up

Experimentental Set-up for Zeeman Experiment

⦁ Tmax: 74%
⦁ HBW: 8nm
5. Polarizer with lens, PL-01
6. Optical Bench: OB-01
7. CCD Camera: CAM-700 (High Resolution CCD Camera)
8. Telescope with Focussing Lens: FL-01
9. Monitor 17": TV-17
10. Electromagnet, EMU-50T (50mm diameter pole piece)
11. Constant Current Power Supply, DPS-50 (Suitable for EMU-50T)
12. Digital Gauss meter, DGM- 202 (For measurement of magnetic field)

The experimental set-up is complete in all respect

Result

The interference pattern is in the form of circular rings. These are split when the magnetic field is switched on. The amount of splitting depends on the external magnetic field, charge to mass ratio of electron and Lande's g- factors of the electronic energy levels involved in the transition. These later quantities can be obtained from this experiment.
