I understand how the wave equation works, and therefore how light moves through the EMF; this question is not about that mechanism.
But when a charge moves in space, information about its location travels outward at the speed of light, altering the field strength of the EMF. What is the mechanism by which this information moves? Is it also the wave equation?
In my classical electromagnetism texts, Maxwell's equations simply state that the information about changes in charge density/location travels through the field at the speed of light, but do not explain the mechanism.
