Many people are aware of a laser. They see laser pointers when showing things on a board at a board meeting. The laser will produce a stream of light. It does this by optical amplification. It is produced by emitting the light using electromagnetic radiation. Wavelength, phase and polarization are related to this emission of light. Since the laser light does not change due to this polarization, it emits a steady constant stream of light. A photon is an elementary particle.

There is no rest mass for a photon when it is at rest. The photon has a charge of one and a spin of one. The characteristic of the light waves from a laser that is not true is that the waves have higher photon energies than light waves of the same frequency from a laser.
