Radio

Radio is a way of sending sound through the air using signals. It works by using a special machine called a radio transmitter to send the sound of music, news, and more from one place to another. The sound is sent in waves of energy, called radio waves, that travel through the air and can be picked up by a radio receiver. The radio receiver then turns the radio waves back into sound. This way, people all over the world can hear the same radio station no matter where they are!
