Radio

Radio is a technology and medium that transmits audio content through electromagnetic waves. It operates by converting sound, such as music or voice, into radio waves, which can be broadcast over varying distances. Radio signals travel through the air and are received by radio receivers that decode the waves back into sound. The medium encompasses various formats, including AM (Amplitude Modulation) and FM (Frequency Modulation), each with distinct properties for sound quality and broadcasting range. Radio serves diverse functions, including entertainment, information dissemination, emergency communications, and public service announcements. It has historically played a significant role in mass communication and continues to be an influential platform for radio shows, news, and music broadcasting.
