Get the concept of: atomic Bohr model, the quantization of energy levels, electron spin, Bohr magneton, the interference of electromagnetic waves, Fabry-Perot
Experiment: Zeeman effect is called the separation of spectral lines of atoms and molecules in a magnetic field. The simplest is the splitting of one spectral line into three components, called normal Zeeman effect ". With the help of a Fabry - Perot studied the splitting of the red cadmium line (643.8 nm), on the basis of the results calculated value of the Bohr magneton.
