Description
Zeeman effect is an optomagnetic device in which a source of line spectrum prefavourly monochromatic source is placed between the poles of electromagnet. On applying the suitable magnetic field, the spectral line splits into sub components which have wavelength different from its main / original wavelength. The apparatus should have:
- Constant deviation spectrograph
- Calibration of drum: 400 nm to 700 nm
- Least count of calibration: 1 nm
- Constant deviation prism made of optical glass having refractive index – 1.71
- Electromagnet should have field strength 10 KG at a gap of 10 mm Between its poles
- Pole pieces dia.: 50 mm; length: 200 mm
- One end of pole pieces is tapered (tapered dia. 25 mm)
- Other end is threaded and provided with a mechanism to move pole pieces back & forth to vary the gap between them
- Digital and stabilized power supply (30 volt; 10 amp) for above electromagnet.
- Neon discharge tube of suitable capillary thickness
- Wooden stand for holding the above discharge tube
- High voltage transformer (Range: 1-4.5 KV) to run the above discharge tube.
- Digital gauss meter (Range: 2-20 KG)
- Is required to measure the applied magnetic field
- A micrometer eyepiece (measuring range: 0-15 mm) should have least count 0.01 mm
- Fabry-Perot etalon (clear aperture 25 mm) should be provided with level screws.
