<P> Radio waves were first predicted by mathematical work done in 1867 by Scottish mathematical physicist James Clerk Maxwell . Maxwell noticed wavelike properties of light and similarities in electrical and magnetic observations . His mathematical theory , now called Maxwell 's equations , described light waves and radio waves as waves of electromagnetism that travel in space , radiated by a charged particle as it undergoes acceleration . In 1887 , Heinrich Hertz demonstrated the reality of Maxwell 's electromagnetic waves by experimentally generating radio waves in his laboratory , showing that they exhibited the same wave properties as light : standing waves , refraction , diffraction , and polarization . Radio waves , originally called `` Hertzian waves '' , were first used for communication in the mid 1890s by Guglielmo Marconi , who developed the first practical radio transmitters and receivers . </P>
