Hydrogen atom from excited state comes to the ground state by emitting a photon of wavelength λ. If R is the Rydberg constant, the principal quantum number n of the excited state is
- \(\sqrt{\frac{\lambda R}{\lambda R-1}}\)
- \(\sqrt{\frac{\lambda}{\lambda R-1}}\)
- \(\sqrt{\frac{\lambda R^{2}}{\lambda R-1}}\)
- \(\sqrt{\frac{\lambda R}{\lambda-1}}\)
Answer
(A) R R-1
