Radio is the transmission of signals, by modulation of electromagnetic waves
with frequencies below those of visible light. Electromagnetic radiation travels
by means of oscillating electromagnetic fields that pass through the air and
the vacuum of space. Information is carried by systematically changing (modulating)
some property of the radiated waves, such as amplitude, frequency, or phase.
When radio waves pass an electrical conductor, the oscillating fields induce
an alternating current in the conductor. This can be detected and transformed
into sound or other signals that carry information. - Wikipedia
