Radio waves and Microwaves Radio communications Radio waves are used to broadcast radio or television signals from transmitters‚ which are then converted into electrical signals with an aerial (which is made out of metal to absorb the radio waves) so you can hear and see them. When done so the aerial converts this wave into an electrical signal (because of the electromagnetic waves energy exciting particles in the aerial and causing them to oscillate/vibrate and thus create an electrical current)
