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.
