AM Radio, or Amplitude Modulation Radio, is a type of radio broadcasting that varies the strength of the signal to transmit sound. It operates on medium and long wave frequencies, allowing it to cover large distances, especially during the night when atmospheric conditions improve reception. AM Radio is commonly used for talk shows, news, and sports broadcasts. While it has been largely overshadowed by FM Radio and digital platforms, it remains popular in many areas due to its simplicity and accessibility, making it a reliable source of information for listeners.
