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.
Describtion Of The Experimental Set-Up
Experimentental Set-up for Zeeman Experiment
The set-up consists of the following:
1.High Resolution Fabry Perot Etalon, FP-01
2.Mercury Discharge Tube, MT-01 (Low Pressure Mercury Discharge Tube)
3.Power Supply for MT-01, MTPS-01 (High Voltage Power Supply for Discharge Tube)
4.Narrow Band Interference Filter, IF-01
5.Polarizer with lens, PL-01
6.Optical Bench: OB-01
7.CCD Camera: CCD-01 (High Resolution CCD Camera)
8.Telescope with Focussing Lens: FL-01
10.Electromagnet, EMU-50T (Specifications as per data sheet)
11.Constant Current Power Supply, DPS-50 (Specifications as per data sheet)
12.Digital Gaussmeter, DGM-102 (Specifications as per data sheet)
The experimental set-up is complete in all respect.
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 factors of the electronic energy levels involved in the transition. These later quantities can be obtained from this experiment.
The result of this unit are within 5% of the standard value.
