Photon: Day 2, P3
Photon: Day 2, P3
Multiple energy levels. We add a new species of atom that has two excited states. The first excited state has the same energy as the excited state of the object ball atom and the second excited state has the same energy as the excited state of the cue ball atom. Transitions between any two levels are allowed, so the photons emitted when the atom goes from the second excited state to the ground state are ones we have not seen before.
