How to Explain the Non-Zero Mass of Electromagnetic Radiation Consisting of Zero-Mass Photons
Gabovich, Alexander M.; Gabovich, Nadezhda A.
European Journal of Physics, v28 n4 p649-655 Jul 2007
The mass of electromagnetic radiation in a cavity is considered using the correct relativistic approach based on the concept of a scalar mass not dependent on the particle (system) velocity. It is shown that due to the non-additivity of mass in the special theory of relativity the ensemble of chaotically propagating mass-less photons in the cavity has a finite overall mass.
