These radiations are just like light, microwaves, infrared, ultraviolet, only with different frequencies (or wavelengths). They are stimulated and received by those dishes that you see and receivers (i.e antenna). Same thing goes for phones...

In short, the discovery of electricity led to the study of it for any purpose imaginable from communications to physical therapy to mechanics. The telegraph would transmit electrical pulses (long and short) over a conductive wire and an alphabet of dashes and dots was created to utilize this means of communications. Radio was discovered by combining electric and magnetic waves of energy to produce an electromagnetic signal that could be tuned to transmit or receive different frequencies. Telegraph http://en.wikipedia.org/wiki/Electrical_telegraph Radio http://en.wikipedia.org/wiki/Radio P.S. If you really want to learn about the mechanics of radio technology I suggest building one. I made one when I was younger and it was a good experience, but I believe they sell radio building kits now so it shouldn't be as difficult gathering up all the materials.<br><b>References : </b><br> That would take half a day to answer so I will refer you to a couple useful links through wikipedia.
