Radio is a technology and medium that allows for the transmission and reception of audio signals through electromagnetic waves. This communication method enables the broadcasting of music, news, talk shows, and other forms of entertainment or information to wide audiences. The fundamental operation involves converting sound into electrical signals that are modulated onto radio waves, which can then be transmitted over distances. Receivers, typically in devices known as radios, detect these waves and convert them back into sound, allowing listeners to access content without needing a physical connection to the source. Radio can operate on various frequency bands, including AM (Amplitude Modulation) and FM (Frequency Modulation), each with distinct characteristics and uses. Radio also encompasses various formats, including traditional broadcast radio, internet radio, and satellite radio, expanding its reach and accessibility in the modern world.
