Experimental Set-up for Zeeman Experiment

The set-up consists of the following:

• High Resolution Fabry Perot Etalon.
• Mercury Discharge Tube, (Low Pressure Mercury Discharge Tube)
• Power Supply for (High Voltage Power Supply for Discharge Tube)
• Narrow Band Interference Filter
•  Central Wave Length: 546nm
•  Tmax: 74%
•  HBW: 8nm
• Polarizer with lens
• Optical Bench:
• CCD Camera: (High Resolution CCD Camera)
• Telescope with Focussing Lens:
• Monitor
• Electromagnet
• Constant Current Power Supply
• Digital Gaussmeter

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 factors of the electronic energy levels involved in the transition. These later quantities can be obtained from this experiment.
The result of this unit is within 5% of the standard value.
