An excited atom emits a photon of energy E when an electron changes from energy level n = 3 to n = 2. In order for the same electron to change directly from energy level n = 2 to n = 3, it may A absorb a photon with energy E B absorb a photon with energy 2E Cemit a photon with energy 3E Demit a photon with energy
