An electron in an excited state of a hydrogen atom emits two photons in succession, the first at 2624 nm and the second at 97.20 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?

Activity 26-5. Atomic spectra [Accompanies Section 26-5] A certain type of atom (not hydrogen) has three energy levels numbered 1, 2, and 3, as shown in the upper illustration. There are three possible transitions between these levels that lead to emission of a photon: 3 → 1, 3 → 2, and 2 → 1. The lower illustration shows the emission spectrum from a gas of these atoms. There are three emission lines, A, B, and C. (a) Rank the photons...
