Radio is a technology that allows for the wireless transmission of audio signals, such as music, news, and talk shows, over long distances. It works by converting sound into electromagnetic waves (radio waves) that can travel through the air and be received by radio receivers, such as car radios, home radios, or portable devices. These waves are transmitted via radio stations that use specific frequencies to broadcast their signals.
