Radio, on the other hand, requires no such(prenominal) physical connection. It relies on the radiation of energy from a contagion antenna in the form of radio waves.

These radio waves, traveling at the speed of light (300,000 km/sec; 186,000 mi /sec), carry the information. When the waves arrive at a receiving antenna, a little electrical voltage is produced.
