If you fluctuate the electric field, you therefore create a wave. You can think of it as space being permeated everywhere by an electric field; your circuit just creates a disturbance in it, like disturbing the surface of water. The disturbance travels away at the speed of light, like ripples in a pond. philippines clothes brand
