In 1864 Scottish mathematical physicist James Clerk Maxwell proposed a comprehensive theory of electromagnetism, now called Maxwell's equations. Maxwell's theory predicted that coupled electric and magnetic fields could travel through space as an "electromagnetic wave". Maxwell proposed that light consisted of electromagnetic waves of short wavelength, but no one had bee… WebHeinrich Hertz. To produce a radio wave, Hertz used a high voltage induction coil that produced an AC voltage signal with a frequency of about 300 million hertz. The high voltage made it possible charges to cross a narrow gap between between two brass spheres at the ends of a semi-circular conducting loop, creating sparks.
