The absorption lines in the infrared portion of the spectrum of a star that are produced by hydrogen are from the Balmer series. The Balmer series were discovered by Johann Balmer in 1885.
The n4-n2 transition of hydrogen is in the cyan, with wavelength of 486.1 nm. blue = als
The "Balmer Series" includes the visible spectrum of light from hydrogen ... fourwavelengths, 410 nm, 434 nm, 486 nm, and 656 nm, that correspond to emissionsof photons by electrons in excited states transitioning to the quantum level describedby the principal quantum number n equals 2. (There are also a number of ultravioletBalmer lines with wavelengths shorter than 400 nm.)Of the four visible Balmer lines, the one with the longest wavelength ... 656 nm ...is the one with the lowest energy per photon. It appears quite red.
yes. in the case of hydrogen atom jumping of an electron from 6th level to 2nd level cause balmer series
The particular colors emitted by an element reflect the exact amounts of energy that electrons orbiting the hydrogen nucleus give off when they drop from higher energy positions further from the nucleus to lower energy positions closer to the nucleus. Since hydrogen is so small and has so few orbitals, it has only four colors that it emits on the Balmer Series. Elements with high atomic numbers have many more orbitals and thus many more colors.
The Balmer series is a section of the hydrogen atomic emission line spectrum. They show the wavelengths of light emitted when electrons transition back to the n = 2 quantum level.
LBP Spectrum?
I believe it to be the Balmer Series.
The absorption lines in the infrared portion of the spectrum of a star that are produced by hydrogen are from the Balmer series. The Balmer series were discovered by Johann Balmer in 1885.
In ascending order of the lower energy state involved in the transition, the first six families of lines in the hydrogen spectrum are: Lyman series Balmer series Paschen series Brackett series Pfund series Humphreys series
Percy Lowe has written: 'Structure of the Balmer series lines in the spectrum of hydrogen'
The n4-n2 transition of hydrogen is in the cyan, with wavelength of 486.1 nm. blue = als
There are two very narrowly separated lines in the excitation spectrum of hydrogen at about 656 nm, which is in the red region of the spectrum. The energy corresponds to a transition from n=3 to n=2 (Balmer series). These are far and away the most intense lines in the visible region of the spectrum, but there is also a line in the blue-green region, and several in the violet part. The overall color of a hydrogen lamp (analogous to a neon lamp, but with hydrogen instead) is a sort of fuchsia or magenta color. See the link in the "related links" section for a picture.

The Balmer Series
With reference to the wikipedia article on this topic: The Balmer series predicts visible light wavelengths with high accuracy. The limiting transition wavelength predicted by the formula, inf -> 2, would be 364.6 nm.
Use the rydberg equation 1/wavelength = 109677[ 1/n one square - 1/n two square ] 109677 is in cm inverse for balmer series n one = 2 and for the fifth line n two = 7 putting them in the equation we get = 397 nm lies in the violet region of light
