AM Radio

AM radio, short for Amplitude Modulation, is a type of radio broadcasting that varies the strength (amplitude) of the audio signal to transmit sound. It allows stations to communicate over long distances, especially at night when the waves can travel farther due to atmospheric conditions. AM radio primarily broadcasts spoken content, news, and music. While it has a broader reach than FM radio, it generally offers lower sound quality and can be more susceptible to interference from electrical devices. AM radio remains a vital medium for news and emergency broadcasting.
