Rydberg Equation Calculator

Rydberg formula is an equation used in atomic physics for describing the spectral lines wavelength of many chemical elements. This Rydberg Equation was originally discovered by spectroscopists and was explained by Bohr in the year 1913. RH for hydrogen is a physical constant relating to atomic spectra, in the science of spectroscopy. Use this simple online Rydberg Equation Calculator to find the Wavelength of Electromagnetic Radiation Emitted in Vacuum.

Formula:

λvac = R(1/n12 - 1/n22)
Where, λvac = Wavelength of electromagnetic radiation emitted in vacuum R = Rydberg Constant,approximately 1.097 x 107 m-1,
n1, n2 = Integers greater than or equal to 1 such that n1 < n2 , corresponding to the principal quantum numbers of the orbitals occupied before and after the 'quantum leap'.

Example

Find the Wavelength of Electromagnetic Radiation Emitted in Vacuum for the principal quantum numbers of the orbitals n1 as 7, n2 as 8 having a Rydberg Constant of 1.0973731568549e+7
λvac = 1.097x107x [1/(7)2 + 1/(8)2]
= 52489.1497

The hydrogen spectrum can be expressed simply in terms of the Rydberg formula. You can find λvac based on the principal quantum numbers and Rydberg constant using this online Rydberg Equation Calculator.
