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'… WebApr 29, 2016 · Longer wavelength, lower frequency waves such as heat and radio have less energy than shorter wavelength, higher frequency waves like X and gamma rays. Not all electromagnetic (EM) radiation is ionizing. Only the high frequency portion of the electromagnetic spectrum, which includes X rays and gamma rays, is ionizing. ...
