We can work out similar series for any ’hydrogen-like’ atom, that is, an atom with Zprotons in the nucleus and a single electron. hydrogen atoms was noticed by Balmer in 1885, and this set of spectral lines is known as the Balmer series. 0973732 10 m-1) and n = 3,4,5,… The three main regions of the hydrogen emission spectrum, as related to series of lines are: Lyman series < 400 nm - ultraviolet region. The energy shells are usually given a letter 'n' to describe the specific energy level. Later on, by careful observation four other spectral series were discovered in the infra-red and ultra-violet regions of hydrogen spectrum. Our eyes can not see the light in the ultraviolet region. " The Balmer series is easy to reproduce in a classroom with a hydrogen discharge tube. As Lyman series is a hydrogen spectral series of transitions. #n_f =2 " "# since the wavelength emitted lies in the visible region of the spectrum ( Balmer series). A more general formula proposed by Ritz which included all four of these series is, in comparable form: l = 91. Hydrogen Spectrum Atomic spectrum of hydrogen consists of a number of lines which have been grouped into 5 series :Lyman, Balmer, Paschen, Brackett and Pfund. These lines occur when an excited electron falls from a higher energy level (n ≥ 4) back down to the n=3 energy level. 2557 Extending hydrogen's emission spectrum into the UV and IR The Lyman series is a series of lines in the ultraviolet region.
