The electron in a hydrogen atom makes a transition from the n = 4 state to the n = 2 state, as indicated in the image. (Figure 1) Figure 1 of 1The figure shows a model of an atom including a nucleus and four circular orbits around the nucleus. An electron jump occurs from the fourth to the second orbit from the center. A photon moves horizontally leftward. Momentum of the photon is directed horizontally rightward, and momentum of the...

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?
