Hydrogen atom from excited state comes to the ground state by emitting a photon of wavelength \lambda. If {\R} is the Rydberg constant, the principal quantum number ' n ' of the excited state is

Correct Answer is : √λRλR−1

\sqrt{\frac{\lambda}{\lambda R-1}}

\sqrt{\frac{\lambda R^2}{\lambda R-1}}

\sqrt{\frac{\lambda R}{\lambda-1}}

\sqrt{\frac{\lambda R}{\lambda R-1}}
