How fast does radio travel
WebThe electromagnetic spectrum includes infrared radiation, microwaves, ultraviolet radiation, X-rays, gamma rays, and radio waves, all of which travel at the speed of light – 299,792,458 meters per second. Radio signals take 8 minutes to travel from the Earth to the Sun, and from 5 to 20 minutes to travel from the Earth to Mars. WebENERGY. An electromagnetic wave can also be described in terms of its energy—in units of measure called electron volts (eV). An electron volt is the amount of kinetic energy needed to move an electron through one volt …
