Artwork: How radio waves travel from a transmitter to a receiver. 1) Electrons rush up and down the transmitter, shooting out radio waves. 2) The radio waves travel through the air at the speed of light. 3) When the radio waves hit a receiver, they make electrons vibrate inside it, recreating the original signal.
In free space the propagation speed of radio waves is the same as that of light, at approximately 300,000 km, so they would arrive there in about 1.3 seconds. The speed falls slightly when passing through a conductor such as an antenna or cable.
