Radio

Radio is a technology that transmits audio signals through electromagnetic waves, allowing sound—such as music, news, or conversations—to be broadcast over distances without physical connections. A radio receiver captures these electromagnetic signals via an antenna, converts them into electrical signals, and then into sound that you can hear through speakers or headphones. It relies on radio frequency spectrum and modulation techniques to transmit various channels. Radio is widely used for communication, entertainment, and information sharing, making it a reliable and accessible medium to reach audiences across different locations.
