An excited hydrogen atom emits a photon of wavelength

\lambda

in returning to the ground state. If

R

is the Rydberg constant, then the quantum number

n

of the excited state is

View answer and explanation

Correct option: C

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

Option C (

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

) is correct because it is the quantum number derived from the Rydberg formula for the given transition.
