Radio signals are made up of two kinds of waves: audio (or sound) waves represent the sounds being sent to the audience and radio frequency waves travel with these sound waves to “carry” them to radios in homes and car, for example. All waves have three parts: a wavelength, an amplitude and a frequency. Each of these parts can be changed to carry information.
