How were radio waves discovered
WebHeinrich Rudolf Hertz (1857-1894) Heinrich Hertz was the first to send and receive radio waves. James Clerk Maxwell had mathematically predicted their existence in 1864. Between 1885 and 1889, as a professor of physics at Karlsruhe Polytechnic, he produced electromagnetic waves in the laboratory and measured their wavelength and velocity. WebIt was a long time after the original development of those first crucial waves. Although the history of radio goes all the way back through the 18 th century, it wasn’t until 1965 that the first radio invented for entertainment emerged. Edwin Howard Armstrong created the frequency modulated “FM” radio in 1933.
