example‚ has two prominent yellow lines (the so-called D lines) at 589.0 and 589.6 nm -- any sample that contains sodium (such as table salt) can be easily recognized using this pair of lines. One of the most dramatic triumphs of astrophysical spectroscopy during the 19th century was the discovery of helium. An emission line at 587.6 nm was first observed in the solar corona during the eclipse of August 18‚ 1868‚ although the precise wavelength was difficult to establish at the time (due to the short
