WebRadio waves are produced when the electric field rapidly changes: there has to be an alternating current. An electric field spreads out into space. When you change an electric field, the distant parts of it do not change instantly. The change is limited by the speed of light. If you fluctuate the electric field, you therefore create a wave.
