    signal is used for two reasons: • To reduce the wavelength for efficient transmission and reception (the optimum antenna size is ½ or ¼ of a wavelength). A typical audio frequency of 3000 Hz will have a wavelength of 100 km and would need an effective antenna length of 25 km! By comparison‚ a typical carrier for FM is 100 MHz‚ with a wavelength of 3 m‚ and could use an antenna only 80 cm long. • To allow simultaneous use of the same channel‚ called multiplexing. Each unique signal can be

    In scientific terms‚ radio is part of the electromagnetic spectrum. Electromagnetic waves push into space going the speed of light‚ which is 300‚000 kilometers per second. When equipment is attached to an antenna‚ the energy becomes radio waves. Some of the energy can be received by another antenna‚ and using a radio receiver‚ the energy connects the transmitter and receiver. Information that is added to the radio waves can be sent as messages known as television programs‚ walkie talkies‚ and other
