▲ [20p-A301-10] Photons can have a constant rest-mass
キーワード：Photon rest-mass, Photon motion, Photon energy
The photoelectric effect proves that the light must be consisting of particles and on the other hand the wave nature of light was shown through the double-slit experiment of Thomas Young. In this experiment, we could observe the interference fringes that justify the light as a wave. But we know that the constant mass of the electron was proven and electron, the same as photon, have interference fringes in the double-slit experiment. Therefore, there is at least one example that a particle with constant rest mass has interference fringes in the double-slit experiment and the removal of constant rest mass, for photon, is not a good solution to answer the observance of interference fringes in the double-slit experiment. In this paper, by considering the constant rest-mass for a photon, we will express its various motions and present its energy equation.
