Web4 apr. 2024 · That means the distance radio waves travel in 1 second in space is 299,792,458 meters (983,571,056 ft). So the speed of radio waves is much higher than that of sound waves. Radio waves can travel through many different media at different speeds. When passing through a medium, the radio wave speed is decreased depending on the … WebThe phase of a radio wave corresponds to how far the signal is offset from a reference point (such as a particular time or another signal). By convention, each cycle of the signal spans 360 degrees. For example, a signal might have a phase shift of 90 degrees, which means that the offset amount is one-quarter (90/360 = 1/4) of the signal.
