Course 3, Session 5, Part 1

The photons that comprise light travel with each other in a beam. One beam of light may combine with one or more other waves of light to form a larger beam. Likewise a beam of light may be composed of several smaller beams of light. Each given beam of light that comprises a said beam of light has photons that came from a source. In our present universe, the source of a beam of light is always a source that initially came from a material phenomenon. Light is formed by the energy expelled from electrons, as stated before. As the source of a beam of light undergoes additional chemical activity, and their activity involves the same frequency of energy that has the same impulse, and this energy is positioned to propagate in the same direction, then the beam of light will continue as it had with the same wavelength and intensity in so long that the electrons of the source are of great enough number to keep producing this light. In so long that there is instability in matter, electrons will be able to release energy. Such a release happens when a given electron is able to find an energy level by which it is more relaxed. The condition of electrons releasing energy is the general activity of instability within the structure of an atom or atoms.
