Electron Excitation
Absorption: Firing an incoming photon (EM wave) hits an electron. The electron absorbs the energy and moves to a higher energy shell further from the nucleus.
Pass-through: If a photon doesn't have the exactly correct amount of energy to excite an electron to a specific higher shell, it is ignored and passes straight through.
Emission: Excited electrons are inherently unstable. They will quickly drop back down to their lower energy level, emitting the extra energy as outgoing EM radiation.
