## What is Balmer series of hydrogen spectrum?

The Balmer series is the name given to a series of spectral emission lines of the hydrogen atom that result from electron transitions from higher levels down to the energy level with principal quantum number 2.

## What does the Balmer series represent?

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.

## What is Lyman Balmer and Paschen series?

The Balmer series releases light in the visible region of the electromagnetic spectrum. The Lyman series, with longer arrows, requires the higher energy of the UV region. The Paschen and Brackett series, with shorter arrows require the lower energy of the IR region. Below is the visible emission spectrum of hydrogen.

## What is the Balmer constant?

Balmer’s formula B is a constant with the value of 3.6450682×10−7 m or 364.50682 nm. m is equal to 2. n is an integer such that n > m.

## What is Balmer formula How does it explain hydrogen spectrum?

The Balmer series of atomic hydrogen. 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.

## What did Balmer discover about the spectrum of hydrogen?

discovery by the Swiss mathematician Johann Jakob Balmer of a simple arithmetic formula relating the wavelengths of lines in the hydrogen spectrum (1885) proved to be the start of intense activity in precise wavelength measurements of all known elements and the search for general principles.

## Why do we use the Balmer series 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.

## What is Paschen series in chemistry?

CHEMISTRY GLOSSARY Paschen series are the series of lines in the spectrum of the hydrogen atom which corresponds to transitions between the state with principal quantum number n = 3 and successive higher states.
