| photon |
The indivisible unit, or quantum, of electro-magnetic radiation. The energy of the photons determines the nature of the radiation, from radio waves at the lowest energy levels, up through infra-red, visible, and ultra-violet light, to X-or gamma-rays, which have energy high enough to ionize atoms.

| photon |
A discrete packet of electromagnetic energy freed by an atom when its electrons shift from an excited state to a less-excited state. The amount of energy released corresponds to a wavelength in the visible part of the electromagnetic wave spectrum. The wavelength of a photon emitted by a laser varies according to the type of gas used inside the optical cavity.
