It arises when n equals two in the formula "inverse wavelength equals Rydberg's constant times the quantity 1 over n squared minus 1 over m squared".
It arises when n equals two in the formula "inverse wavelength equals Rydberg's constant times the quantity 1 over n squared minus 1 over m squared". The first, or alpha, member is at 6563 Angstroms and all other entries are also in the visible spectrum. It was not explained, though, until Bohr's quantum theory of the hydrogen atom.  For ten points, name this spectral line series.
