Radio waves are used to receive and transmit signals between two objects. These waves help to transfer signals from broadcasting stations to televisions and radios, and they are also used to transmit signals for cellular phones.
Radio waves help to convey information from one place to another, such as receiving incoming information from television and radio broadcasting networks. Radio waves are also used in radar and navigational devices placed in spacecraft, boats and planes. Long-range signals, for instance, enable astronauts to communicate with stations on Earth. Radio waves help with navigation by accepting signals from global positioning satellites, and in turn transmit information on an object's location.
