# Rydberg Formula

The Rydberg formula suggests that the observed spectral lines can be grouped into series, the lines of each series being generated when a particular value of n^{2} is used in the Rydberg formula. Rydberg formula is the formula for expressing the wave number of a spectral line.

**The general Rydberg Formula is**,

Rydberg formula = $\frac{1}{\lambda}$ = $\nu$ = R $\left (\frac{1}{n^{2}} - \frac{1}{m^{2}} \right)$.

Where

Since Rydberg formula generates the frequencies of all the spectral lines of the hydrogen atom, it provides a concise analytical summary of the hydrogen spectral data.

**n**and**m**are positive integers and R is the Rydberg constant. The value 109,677 cm^{-1}is called**Rydberg**constant for hydrogen.Since Rydberg formula generates the frequencies of all the spectral lines of the hydrogen atom, it provides a concise analytical summary of the hydrogen spectral data.
