Problem
A hypothetical atom has the following allowed energy levels (relative to the ground state): 0 eV, 1.20 eV, 2.10 eV, 3.30 eV, and 5.40 eV. A spectrometer records an emission line whose photon energy is 2.10 eV. List every pair of energy levels between which an electronic transition could have produced this photon.
