# 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:

λ_{vac} = R(1/n_{1}^{2} - 1/n_{2}^{2})

**Where,**
λ_{vac} = Wavelength of electromagnetic radiation emitted in vacuum
R = Rydberg Constant,approximately 1.097 x 10^{7} m^{-1},

n_{1}, n_{2} = Integers greater than or equal to 1 such that n_{1} < n_{2} , 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 n**_{1} as 7, n_{2} as 8 having a Rydberg Constant of 1.0973731568549e+7

λ_{vac} = 1.097x10^{7}x [1/(7)^{2} + 1/(8)^{2}]

= 52489.1497

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