#### 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 Î»_{vac} based on the principal quantum numbers and Rydberg constant using this online Rydberg Equation Calculator.
