Radio waves do more than just bring music to your radio. They also carry signals for your television and cellular phones. The antennae on your television set receive the signal, in the form of electromagnetic waves, that is broadcasted from the television station. It is displayed on your television screen.
Cathode-ray-type television screens, like the one in the video, create an image on the screen by accelerating charged particles (electrons) using an electric field. The electrons then pass between two steering coils made of copper wire. Currents running through the coils produce magnetic fields.
The TV signal is carried by wire to an antenna, which is often on a high mountain or building. The signal is broadcast through the air as an electromagnetic wave. These waves can travel through the air at the speed of light but not over very long distances.
