What are the spectral lines of hydrogen atoms?
ADDITIONAL INFORMATION:For a hydrogen atom, the spectral lines are given special names. For n’=1 the series is called the Lyman series, which lies in the ultraviolet region. n’=2 is given the name Balmer series which has a few lines in the visible region, n’=3 is the Paschen series lying in the infrared region and there are others for n’=4, 5 and 6 named as Brackett series, Pfund series and Humphrey series respectively.
What is the spectral emission?
We know that spectral emission occurs when an electron transitions from a higher energy state to a lower energy state. The lower energy state is designated as n’ and the higher energy state is designated as n. The spectral lines obtained due to the emissions are grouped into a series according to their lower energy state (n’).

What is the spectrum of electrons in an atom?
When electron in the atom or a molecule is making a transition from higher to lower energy level, it emits the spectrum of frequencies of electromagnetic radiation. This Spectrum is called emission spectrum. Such emission spectrum of hydrogen atom has been divided into different number of spectral series depends on wavelength of emitted electromagnetic waves. These wavelengths can be determined by Rydberg Formula.
