>If photons and electrons travel at the same speed "If" - they do not! https://en.wikipedia.org/wiki/Electron_mobility https://en.wikipedia.org/wiki/Electron_mobility Quoting from the above source... >Typical electron mobility for Si at room temperature (300 K) is 1400 cm2/ (V·s) and the hole mobility is around 450 cm2/ (V·s).[2] However this is besides the point since electric fields in a conductor do move at the speed of light.
