What Is the Lyman Series?

The Lyman series is one of the five spectral line series, which are sequences of wavelengths characterizing the light and electromagnetic radiation emitted by energized atoms. The Lyman series is in the ultraviolet region. The formula’s constant term is the reciprocal of the square of 1, 3, 4 or 5.

The running number n of the Lyman series begins at 2, 4, 5 and 6. The Lyman series is named after its discoverer, Theodore Lyman. The most popular of the spectral line series is the Balmer series, which lies in the visible region. The Balmer series was named after Swiss mathematician Johann Balmer. According to Encyclopaedia Britannica, the three other spectral line series are named after their discoverers, A.H. Pfund, F.S. Brackett and Fredrich Paschen.
