The same spectral line undergoing anomalous Zeeman splitting is observed in direction 1 and, after reflection from the mirror \(M\) (Fig. 6.9 ), in direction 2. How many Zeeman components are observed in both directions if the spectral line is caused by the transition (a) \({ }^{2} P_{3 / 2} \rightarrow{ }^{2} S_{1 / 2}\) (b) \({ }^{3} P_{2} \rightarrow{ }^{3} S_{1} ?\)
