A light wave consists of energy in the form of an electric filed and a magnetic field. The electric and magnetic fields vibrate at right angles (that is, at angles which measure 90 degrees) to the direction in which the light wave is moving. Light has both the electric field and the magnetic field.his is because unlike other types of waves, such as sound waves, water wave â¦ s, etc., light waves do not need a medium to travel through.
Actually, radio waves travel very quickly through space. Radio waves are a kind of electromagnetic radiation, and thus they move at the speed of light. The speed of light is a little less than 300,000 km per second. At that speed, a beam of light could go around the Earth at the equator more then 7 times in a second.
