# Rydberg Equation Calculator

Posted by Dinesh onUse our online **rydberg equation** calculator tool to calculate the wavelength of the light. Rydberg formula predicts the wavelength of light.

A method of determining the **Rydberg constant** is to analyze a graph
of the values of n in the Balmer Series vs. the wavenumber.
Import your data into a plotting program and prepare a plot of
wavenumber vs. 1/n^{2}_{i}, including error bars for the wavenumber.

### Formula:

$\frac{1}{\lambda}=R{Z}^{2}\left[\frac{1}{{{n}_{f}}^{2}}-\frac{1}{{{n}_{i}}^{2}}\right]$

Where,? = Wavelength of the photon

nf = Principle quantum number of final state

ni = Principle quantum number of initial state

RH = Rydberg Constant (1.097x 10

^{7 }m

^{-1})

Z = Number of proton in the nucleus of the element
