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.
Radio waves make the world go around. They make communication and navigation satellites possible, underpin modern aviation, and allow you to access the Internet without wires. One characteristic of radio technology is that traffic flows in only one direction at a time on a specific frequency. That's why pilots, police, and other walkie-talkie users frequently use over as they take turns speaking.
