Learn about the history, principles, types, and facts of radio technology, the transmission and detection of electromagnetic waves through the air or space. Explore the basic physical properties of radio waves, such as frequency, wavelength, and amplitude.
In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter.
