Web29 mei 2024 · Light travels at a blistering 670 million mph — a speed that’s immensely difficult to achieve and impossible to surpass. But some particles are being accelerated … The speed at which energy or signals travel down a cable is actually the speed of the electromagnetic wave traveling along (guided by) the cable. I.e., a cable is a form of a waveguide. The propagation of the wave is affected by the interaction with the material(s) in and surrounding the cable, caused by the presence of electric charge carriers (interacting with the electric field component) and magnetic dipoles (interacting with the magnetic field component). These intera…
