How is radio waves used

WebIn this method, the information is put into a radio wave by varying the amplitude. For example, if all we wanted to do was send 1's and 0's, we could have just two different levels of amplitude that correspond to these numbers--1 being high, 0 being low. F.M. stands for frequency modulation. This time the amplitude is kept constant, it is the ... WebRadio Waves ideally generate using a transmitter and a receiver detects them. Further, the entire process of generating usable electromagnetic waves is done by using an Antenna to transmit energy into space. In addition, from where a receiver picks up the energy and converts it into mechanical vibrations that are heard as Sound waves.
