Product Summary
In this experiment the student observes the interference pattern form a Fabry-Perot interferometer which results from 546.1 nm spectral line of a mercury lamp immersed in a uniform magnetic field. The magnetic field is varied from zero to nearly 1 Tesla.
Initially, the light is viewed along an axis perpendicular to the magnetic field axis. A polarizer is used to show the three lines due to light that is polarized parallel to the field axis and to show the six lines that are polarized perpendicular to the field axis. The pattern may also be viewed along the field axis where the light is circularly polarized.
Finally, the pattern that is polarized perpendicular to the field axis is used to calculate the Bohr magneton. All atomic magnetic moments are integral or half-integral multiples of the Bohr magneton.
PASCO Advantage: In PASCO Capstone software, students can use the video magnifier tool to enlarge the region to see the details of the line splitting. Also, the radius tool needs only three points to define the circle, so even rings that are partially out of view can be measured.
Concepts
- Measure the Zeeman Effect with polarization perpendicular and parallel to the field

Zeeman Effect
In a magnetic field, the spectral lines of atoms split into a number of closely spaced lines. This is called the (anomalous) Zeeman Effect. The Zeeman Effect was very important in the development of Quantum Mechanics, especially...
