How big are radio waves
Radio waves were first predicted by the theory of electromagnetism proposed in 1867 by Scottish mathematical physicist James Clerk Maxwell. His mathematical theory, now called Maxwell's equations, predicted that a coupled electric and magnetic field could travel through space as an "electromagnetic wave". Maxwell proposed that light consisted of electromagnetic waves of very short wavelength. In 1887, German physicist Heinrich Hertz demonstrated the reality of Maxwell'… WebExamples of Radio Waves. 1. Radio Broadcasting. One of the prime applications of radio waves is radio broadcasting. Here, first of all, the sound signal is modulated with the help of various modulation techniques such as amplitude modulation (AM) and frequency modulation (FM). The modulated signal is then encoded, and transmitted in the air ...
