for homework this is my last question on the sheet but I dont get it.

In simple terms: The Zeeman effect is the splitting of spectral lines in a strong magnetic field.
Explanation:
When an external mag-field is applied, sharp spectral lines like the n = 3 -> 2 transition of hydrogen split into multiple very close spaced lines. In terms of history, it was first observed by Pieter Zeeman (hence the name) , this splitting is attributed to the interaction between the mag-field & the magnetic dipole moment associated with orbital angular momentum (take a look also at Bohr's postulates might be interesting). In the absence of the mag-field, the hydrogen energies only depend upon the principal quantum number. Also the emissions will only occur at a single wavelength.
The obvious example is the the Zeeman effect for hydrogen.
The Zeeman effect for the hydrogen atom essentially supported the quantisation of angular momentum which came up from the solution of Schrodinger equation.
