AM radios, or Amplitude Modulation radios, are devices that receive radio signals by varying the amplitude of the broadcast waves. This technology allows listeners to tune into various stations that transmit news, music, and talk shows. AM radio waves can travel long distances, especially at night, making them popular for reaching rural areas. The sound quality of AM radios is generally lower than that of FM radios, as they are more susceptible to interference from electrical devices and atmospheric conditions. Despite this, AM radio remains a vital source of information and entertainment for many people, especially during emergencies when other communication methods may fail.
