WebHow do radio waves carry information? The basic principle is simple. At one end, a transmitter “encodes” or modulates messages by varying the amplitude or frequency of the wave – a bit like Morse code. At the other, a receiver tuned to the same wavelength picks up the signal and ‘decodes’ it back to the desired form: sounds, images, data, etc. WebLight travels through space in waves, like ripples in a pond. Each ripple has a peak and a trough, which is called a cycle. An object emitting radio waves gives off many cycles in a very short period of time. During each cycle, the wave moves a short distance, which is called its wavelength. Radio Frequencies and Astronomy by the Numbers ontario oregon planning and zoning
