2011-12-16 · The Balmer lines are the most well known and observed emission lines in astronomy both being strong lines in the optical and ubiquitous as they arise from recombination to the n= 2 level of the most common element hydrogen. As the atomic structure of hydrogen is so well understood the strength of the emission-line fluxes can be well
The Balmer series of atomic hydrogen. These lines are emitted when the electron in the hydrogen atom transitions from the n = 3 or greater orbital down to the n = 2 orbital. The wavelengths of these lines are given by 1/λ = RH (1/4 − 1/ n2) where λ is the wavelength RH is the Rydberg constant and n is the level of the original orbital.

2018-3-30 · The Balmer thermometer works because the Balmer lines are produced only by hydrogen atoms whose electrons are in the second energy level. If the surface of a star is as cool as the surface of the Sun (about 5800 K) or cooler most of the atoms are in the ground state.
2019-8-7 · The Balmer series is the portion of the emission spectrum of hydrogen that represents electron transitions from energy levels n > 2 to n = 2. These are four lines in the visible spectrum. They are also known as the Balmer lines. The four visible Balmer lines of hydrogen appear at 410 nm 434 nm 486 nm and 656 nm.
