Principle The "Zeeman effect" is the splitting up of the spectral lines of atoms within a magnetic field. The simplest is the splitting up of one spectral line into three components called the "normal Zeeman effect". In this experiment the normal Zeeman effect as well as the anomalous Zeeman effect are studied using a cadmium spectral lamp as a specimen.
Zeeman effect with a variable magnetic system and a CCD camera including the measurement software P2511007
Tasks 1. Using the Fabry-Perot interferometer and a selfmade telescope the splitting up of the central line into different lines is measured in wave numbers as a function of the magnetic flux density. 2. From the results of point 1. a value for Bohr's magneton is evaluated. 3. The light emitted within the direction of the magnetic field is qualitatively investigated.
