Six transitions are possible. The six possibilities are, listed by initial and final quantum levels: 4 to 3 (lowest-frequency light produced because this is the smallest energy drop) 4 to 2 4 to 1 (highest-frequency light produced because this is the largest energy drop) 3 to 2 3 to 1 2 to 1

Work Step by Step

For photons, E = hf, where E is the energy, h is Planck's constant, and f is the photon's vibrational frequency.
