Radio is the transmission of indicators, by modulation of electromagnetic waves with frequencies below these of visible mild Electromagnetic radiation travels by way of oscillating electromagnetic fields that cross by the air and the vacuum of area. Info is carried by systematically changing ( modulating ) some property of the radiated waves, comparable to amplitude , frequency , or part When radio waves move an electrical conductor, the oscillating fields induce an alternating present in the conductor. This can be detected and reworked into sound or other indicators that carry information.
