Radio

Radio is a technology that enables the transmission and reception of signals through electromagnetic waves. It involves the conversion of sound, voice, music, or other audio content into radio waves, which are then broadcast over a specific frequency range through the air. Radio is commonly used for communication, entertainment, and information dissemination. It operates by modulating a carrier wave, allowing the audio signal to be transmitted over various distances, depending on the type of radio (AM, FM, digital). Typically, radio receivers detect these waves and convert them back into audible sound for the listener. Additionally, radio plays a significant role in broadcasting news, music, talk shows, and other media content to a wide audience.
