The first line in Lyman series has wavelength λ. Ans: (a) Sol: Series Limit means Shortest possible wavelength . And, this energy level is the lowest energy level of the hydrogen atom. The so-called Lyman series of lines in the emission spectrum of hydrogen corresponds to transitions from various excited states to the n = 1 orbit. The first line in the spectrum of the Lyman series was discovered in 1906 by Harvard physicist Theodore Lyman, who was studying the ultraviolet spectrum of electrically excited hydrogen gas. Can you explain this answer? For the Balmer series, n 1 is always 2, because electrons are falling to the 2-level. The first line in each series is the transition from the next lowest number in the series to the lowest (so in the Lyman series the first line would be from n=2 to n=1) and the second line would be from from the third lowest to the lowest (in Lyman it would be n=3 to n=1) etc etc. The formation of this line series is due to the ultraviolet emission lines of … For example, in the Lyman series, n 1 is always 1. 3.6k SHARES. 6.8 The first line in the Lyman series for the H atom corresponds to the n = 1 → n = 2 transition. 4. 812.2 Å .
