- Photons are light particles. Wave physics govern how photons travel, but, they are detected as particles.
- Waves can interfere with one another in a destructive or a constructive mode.
- The double slit experiment proved that light propagates as a wave. The wave length of the light determines its color. Velocity of the light determines its brightness.
- Light reflects, or refracts.
- Light produces the colors of the rainbow. The color red is the longest wavelength, followed by orange, yellow, green, blue, indigo (purple), and ultra violet (the shortest). ROYGBIV.
- Relativistic quantum fields are a unified field of electromagnetism.
- Quantum field theories are replacing the classic electromagnetic field theories with a quantum formulation. Quantum electrodynamics determines that a spinning charge will create an electrodynamic field.
- Dirac’s theory predicted the existence of antimatter, in 1932.
- The positron is a form of antimatter. It is the anti electron. Most particles have been proven to have an antimatter particle. Antimatter is identical to matter particles in many ways.
- Matter and anti-matter particles have opposite charges. Anti-matter and matter particles are antagonistic substances, combined, they create a high burst of energy.
- Schroeder’s equation was the first quantum revolution. The second quantum revolution was the discovery that matter came in quantum chunks.
- Not all photons are created equal. In quantum electrodynamics, there isn’t a smooth, continuous electronic field. The two electrons are emitting and absorbing a broth of photons. Photons can jump from one to another, in quantum electrodynamics..
