	Not all radiant energy is visible (see figure 1). Only photons within a very small range of energies can be seen by people, commonly known as visible light. Photons with lower energies are found in microwaves, radio waves, and as [[infrared]] radiation (which is felt as [[heat]]). Photons with higher energies are found in [[ultraviolet]] rays, in [[x-ray]]s, and in [[gamma decay\|gamma ray]]s.		Not all radiant energy is visible (see figure 2).
