The antenna emits electromagnetic waves that your radio turns into sound waves.

   Undulatory phenomena are part of the world around us. Sounds reach us by means of waves, we perceive light as waves; you could say that it is through waves that we get almost all the information that we possess. 

   By analysing undulatory phenomena as simple as waves extending across a puddle or the peaks and troughs propagated along a shaking rope, we will try to study the general characteristics of all undulatory movements.
