The Balmer series , or Balmer lines in atomic physics , is one of a set of six named series describing the spectral line emissions of the hydrogen atom. The Balmer series is calculated using the Balmer formula, an empirical equation discovered by Johann Balmer in The visible spectrum of light from hydrogen displays four wavelengths , nm , nm, nm, and nm, that correspond to emissions of photons by electrons in excited states transitioning to the quantum level described by the principal quantum number n equals 2. The series continues with an infinite number of lines whose wavelengths asymptotically approach the limit of After Balmer's discovery, five other hydrogen spectral series were discovered, corresponding to electrons transitioning to values of n other than two.

Series limit of balmer series

A sequence of absorption or emission lines in the visible part of the spectrum, due to hydrogen; also known as Balmer lines. Balmer absorption lines are caused by jumps of electrons from the second energy level to higher levels, and emission lines when the electrons drop back to the second energy level. They are named after the Swiss mathematician Johann Jakob Balmer — See also hydrogen spectrum. From: Balmer series in A Dictionary of Astronomy ».

The emission spectrum of atomic hydrogen has been divided into a number of spectral series , with wavelengths given by the Rydberg formula. These observed spectral lines are due to the electron making transitions between two energy levels in an atom. The classification of the series by the Rydberg formula was important in the development of quantum mechanics. The spectral series are important in astronomical spectroscopy for detecting the presence of hydrogen and calculating red shifts. A hydrogen atom consists of an electron orbiting its nucleus. The electromagnetic force between the electron and the nuclear proton leads to a set of quantum states for the electron, each with its own energy.

Series limit of balmer series

In an amazing demonstration of mathematical insight, in Balmer came up with a simple formula for predicting the wavelength of any of the lines in atomic hydrogen in what we now know as the Balmer series. Three years later, Rydberg generalized this so that it was possible to determine the wavelengths of any of the lines in the hydrogen emission spectrum. Rydberg suggested that all atomic spectra formed families with this pattern he was unaware of Balmer's work. It turns out that there are families of spectra following Rydberg's pattern, notably in the alkali metals, sodium, potassium, etc. The various combinations of numbers that can be substituted into this formula allow the calculation the wavelength of any of the lines in the hydrogen emission spectrum; there is close agreement between the wavelengths generated by this formula and those observed in a real spectrum. Is there a different series with the following formula e.
