How can interfering light waves transport particle characteristics? Up to now it was supposed that wave-particle duality was a quantum mechanical phenomenon which was not accessible to any classical explanation. The present article is disproving this assumption, by showing o n e single case which is entirely subject to a classical explanation: Photons in vacuum. The suggested classical explanation of wave-particle duality is simple, and it is deriving directly from special relativity: The particle characteristics are transported directly from A to B, without any intermediate of spacetime, because the interval is zero. The observed wave is a sort of placeholder in our spacetime.
Photons and elementary particles display the properties of particle as well as of wave known as Wave Particle Duality. Quantum Theory could not explain Wave Particle Duality only due to the belief that photon has no mass and accepted Wave Particle Duality as reality of quantum scale particles. “Experimental Proof of Mass in Photon” [1] discovered Inertial Force developed by the photons on Reflection. This Inertial Force is developed in the spinning photon from inside due to the mass of photon. These experiments also discovered that the centre of mass of photon was different from the centre of photon. Such presence of mass in a photon developing Inertial Force from within the photon gifts special properties to display Wave Particle Duality, Interference and Polarization etc. These phenomena are explained in this work which could not be explained by the Quantum Theory earlier. This work also confirms mass in photon based on both Newtonian and Special Theory of Relativity. New equations of true mass of photon are also derived.
