Based on the Maxwell’s electromagnetic theory and Planck’s energy quantum theory, a new theory of energy and mass relation of a photon in wave motion was developed. The theory provided a way of measuring the mass of a photon in wave motion. With innovative incorporation of chemical bond theory, a new theory of photon molecule with π chemical bond and σ chemical bond at extreme conditions was also developed. This theory clearly illustrated the mechanism of mass generation of matter as the proceeding of photon’s polymerization based on the energy conservation. It provided the sound explanation of the generation of photon string and photon membrane as the building block of the matter. It also articulated how a photon to form a stable photon dipole from spin point-charges. It also elucidated the intrinsic nature of electromagnetic waves attributed to the different pole distance of photons.
