Question
In a normal Zeeman effect experiment, spectral splitting of the line at the wavelength 643.8 nm corresponding to the transition 5 1D2 → 5 1P1 of cadmium atoms is to be observed. The spectrometer has a resolution of 0.01 nm. The minimum magnetic field needed to observe this is (me = 9.1 * 10-31 kg, e = 1.6 * 10-19C, c = 3 * 108 m/s)
