Web24 feb. 2012 · Extent of human radio broadcasts Humans have been broadcasting radio waves into deep space for about a hundred years now, since the days of Marconi. That, of course, means there is an ever-expanding bubble announcing Humanity's presence to anyone listening in the Milky Way. WebRadio waves are electromagnetic waves that propagate with a speed near 300,000 km/s. Electromagnetic waves have a frequency and wavelength. There are different type of waves, with high and low frequency. Even visible light is an electromagnetic wave, that has a very short wavelength.
