Radio broadcasting is the transmission of audio content through electromagnetic waves to reach a wide audience. It involves the use of radio waves to send signals from a transmitter to a receiver, such as a radio or a smartphone. This technology allows people to listen to music, news, and talk shows from various radio stations. The process begins with content creation, where broadcasters produce programs that are then sent out over the airwaves. Listeners can tune in to their favorite stations at specific frequencies, making radio a convenient and accessible form of entertainment and information.
