e following stars (from top to bottom): Castor, Procyon, Capella, Pollux and Betelgeusse. (From Sky and Telescope magazine, May 2000)The emission spectra in Fig. 2 are centered at the 4861 angstrom line of hydrogen. Fig. 3 shows the emission spectrum of atomic hydrogen (a) and molecular hydrogen (b)Fig. 3 a. The emission spectrum of atomic hydrogen consists of a few widely spaced bands. b. molecular hydrogen gives of light at more frequencies and thus has more bands in its spectrum (From Chemistry by Addison-Wesley)....
