What were the principal quantum numbers of the initial and, Ask an Expert

Academics

An electron in an excited state of a hydrogen atom emits two photons in succession, the first at 486.0 nm and the second at 121.5 nm, to return to the ground state (n=1). For a given transition, the wavelength of the emitted photon corresponds to the difference in energy between the two energy levels.

What were the principal quantum numbers of the initial and intermediate excited states involved?

(Enter the number of the higher atomic orbital in the first answer box.)
