Problem
The members of a class of stars known as Ap stars are distinguished by their strong global magnetic fields (usually a few tenths of one tesla).22 The star HD215441 has an unusually strong magnetic field of 3.4 T. Find the frequencies and wavelengths of the three components of the Hα spectral line produced by the normal Zeeman effect for this magnetic field.
