Suppose you had a collection of a large number of hypothetical quantum objects, each of whose individual energy levels were -4.5 ev, -2.9 ev, -2.3 ev, and -1.2 ev. if nearly all of these identical objects were in the ground state, what would be the energies of dark spectral lines in an absorption spectrum if visible white light (1.8 to 3.1 ev) passes through the material?
