Radios use radio waves, a fairly recent discovery, to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, or phase. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.

The ability to quickly and reliably transmit information across vast distances has led radio to becoming ubiquitous throughout the universe. It has become a crucial aspect of modern life. The following are uses of major note.
Drones have proved useful time and again in their short existence thus far, although they have some serious limitations.
