Hydrogen atom from excited state comes to the ground state by emitting a photon of wavelength $\displaystyle \lambda$. The value of principal quantum number ' $\displaystyle n$ ' of the excited state will be : ( R : Rydberg constant)
Official answer
(2)
$\displaystyle \sqrt{\frac{\lambda \mathrm{R}}{\lambda \mathrm{R}-1}}$
