"In a vacuum, electromagnetic waves travel at the speed of light, commonly denoted c."
I would expect that in air, that the photon from the light source and the perturbance of the electric field from the charge to reach the detector at the same time.
Confused. Are you saying that, if we took a light bulb (off) and a metal rod (0 charge) beside on another.
Then were somehow able to turn the light bulb on and apply a charge to the that rod at the same time. While also having a detector that can sense a photon and a change in electric field some equal distance away from the bulb and rod.
Then the photon (from the bulb) would reach our detector before the detection of the change in electric field (from the rod)?
Let's suppose the medium is just plain air, and not particularly humid.
Would be nice to link to reflections.
Additionally, any thought given towards incorporating standard cataloging systems like Library of Congress?
