What are the $Zeeman$ and $Stark$ effects? What is their significance?
(N/A) The $Zeeman$ effect refers to the splitting of spectral lines in the presence of an external magnetic field.
The $Stark$ effect refers to the splitting of spectral lines in the presence of an external electric field.
These effects demonstrate that spectral lines are not single lines but consist of closely spaced components,providing evidence for the quantization of energy levels.
