KipIngram Posted June 4, 2017 Posted June 4, 2017 Photons by definition travel at c, since they have no rest mass. Once they exist, they move, regardless of what's going on at the source. Also, from a classical view, Maxwell's equations show that EM waves propagate, again without reference to their source.

KipIngram Posted June 4, 2017 Posted June 4, 2017 Yes, they carry momentum and energy, the dynamics of which lead to propagation.
Roger Dynamic Motion Posted June 4, 2017 Author Posted June 4, 2017 Yes, they carry momentum and energy, the dynamics of which lead to propagation.the Energy comes from where to propagate
Strange Posted June 4, 2017 Posted June 4, 2017 the Energy comes from where to propagate From the source.
Roger Dynamic Motion Posted June 4, 2017 Author Posted June 4, 2017 From the source.good answer ah ah
