# Problem: What is the wavelength of the line corresponding to n=4 in the Balmer series?

###### FREE Expert Solution

Wavelength and the energy levels in the Balmer series are related by:

$\overline{)\frac{\mathbf{1}}{\mathbf{\lambda }}{\mathbf{=}}{\mathbf{R}}{\mathbf{\left(}}\frac{\mathbf{1}}{{\mathbf{2}}^{\mathbf{2}}}{\mathbf{-}}\frac{\mathbf{1}}{{\mathbf{n}}^{\mathbf{2}}}{\mathbf{\right)}}}$

Rydberg constant, R = 1.097 × 107 m-1
