Scattering Experiment

Which one of the following options correctly gives Rydberg’s formula for the hydrogen spectrum?

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

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

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

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