Abstract
The mass density and energy density of visible photon is calculated as and , respectively. Moreover it is also observed that mass density and energy density of photon depend upon photons mass, wavelength, volume and energy. This is clear from figure 1, figure 2 and literatures. Therefore the mass density and energy density of photon varies with masses of photon, wavelength, volume, etc.
Highlights
The formulations of the theory that assume the rest mass of photon is zero, failed to lead to a covariant description of the light wave
If we study deeply on the cross section area, it is observed from table 2 that cross sectional Since we have density formula
The calculation show that the mass density is of order of and energy density is of order of
Summary
The formulations of the theory that assume the rest mass of photon is zero, failed to lead to a covariant description of the light wave. Uncertainty principle the upper limit of rest mass photon is estimated by equation and given a numerical value g at universe age 1010 years. This mass is extremely difficult to detect, Coulomb’s law and Ampere’s law, longitudinal electromagnetic waves and Yukawa potential of magnetic dipole fields was studied seriously to find the mass of photon. Gravitational deflection of massive photons support the hypothesis for setting the limits of photon mass and from theory of general relativity for photon has a nonzero rest mass, deflection angle is given by (8). The demonstration and experiment show photons masses near [18]
