FM Radio, or Frequency Modulation Radio, is a method of broadcasting audio signals through radio waves. It works by varying the frequency of the carrier wave to encode sound information, which allows for clearer sound quality and less interference compared to AM (Amplitude Modulation) radio. FM radio is commonly used for music and talk shows, providing listeners with a wide range of programming options. FM radio stations operate within specific frequency ranges, typically between 88 and 108 megahertz (MHz). Listeners can access these stations using FM radios, which are found in various devices, including car stereos and portable radios. The technology has been popular since the 1930s and continues to be a significant medium for entertainment and information.
