Problem

A simplified atomic spectrum shows two emission lines. One line corresponds to a 1.89 eV1.89\,\text{eV} photon emitted when the atom drops from level 2 to level 1. The other corresponds to a 0.97 eV0.97\,\text{eV} photon emitted when the atom drops from level 3 to level 2. What is the energy of level 3 relative to level 1? (a) 1.89 eV1.89\,\text{eV} (b) 0.92 eV0.92\,\text{eV} (c) 2.86 eV2.86\,\text{eV} (d) 2.50 eV2.50\,\text{eV}
