FM radios, or Frequency Modulation radios, are devices that receive radio signals transmitted over the airwaves. They work by varying the frequency of the radio wave to encode sound information, which allows for clearer audio quality compared to AM (Amplitude Modulation) radios. FM radios are commonly used to listen to music, news, and talk shows broadcast by various radio stations. FM radio stations operate within specific frequency ranges, typically between 88.0 and 108.0 megahertz (MHz). Listeners can tune in to their favorite stations using a dial or digital display. Many modern devices, including smartphones, car stereos, and portable speakers, come equipped with FM radio capabilities, making it easy to access a wide variety of programming.
