An excited-state hydrogen atom 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?

Question

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

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

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

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