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 1885.

The four visible hydrogen emission spectrum lines in the Balmer series. H-alpha is the red line at the right. The Balmer series includes the lines due to transitions from an outer orbit n > 2 to the orbit n' = 2. Named after Johann Balmer, who discovered the Balmer formula, an empirical equation to predict

This series of the hydrogen emission spectrum is known as the Balmer series. This is the only series of lines in the electromagnetic spectrum that lies in the visible region. The value, 109,677 cm-1, is called the Rydberg constant for hydrogen.

The Balmer series is particularly useful in astronomy because the Balmer lines appear in numerous stellar objects due to the abundance of hydrogen in the universe, and therefore are commonly seen and relatively strong compared to lines from other elements.

2025年1月25日 · Balmer series is the second series of spectral series of hydrogen spectrum. It was found out in the visible region in 1885 by the Swiss mathematician and physicist Johann Jakob Balmer . In the Balmer series, the value of n 1 is always 2, which represents the ground state of the hydrogen atom.

Four bright lines are found in the visible region of the atomic spectrum of hydrogen. The experimental values of their wavelengths are 6563 Å, 4861 Å, 4341 Å, and 4102 Å. These four lines are collectively known as the Balmer series of the hydrogen spectrum.

In 1885, J. J. Balmer, a lecturer in a ladies' college in Switzerland, devised a simple formula relating the wavelengths of the lines in the visible region of the atomic hydrogen spectrum to the natural numbers, and these lines have since been referred to as the Balmer series and have been denoted by H α α, H β β, H γ γ,...,starting at the long ...

2019年8月7日 · 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 .

Historically, the spectral lines of hydrogen have been categorized as six distinct series. The visible portion of the hydrogen spectrum is contained in the Balmer series, named after Johann Balmer who discovered an empirical relationship for calculating its wave-lengths [2].

The Balmer Series in Hydrogen and Deuterium Introduction: You will be repeating an experiment that won the Nobel Prize. First, here’s some background. In 1885 a Swiss schoolteacher named Johannes Balmer observed that the wavelengths of the visible spectral lines of the
