What is the full form of AM radio?
2 Answers
The full form of **AM radio** is **Amplitude Modulation radio**.
Let me break it down:
- **Amplitude Modulation (AM)** refers to the method of broadcasting radio signals. In this method, the amplitude (strength) of the radio wave is varied in accordance with the audio signal (the information, such as voice or music) being transmitted.
- **Radio** refers to the technology that uses electromagnetic waves to transmit information (such as music, speech, or data) through the air, using specific frequencies.
In AM radio, the frequency of the carrier wave stays the same, while the amplitude changes to encode the sound information. It is one of the oldest forms of broadcasting, dating back to the early 20th century, and is widely used for talk radio and news because it can travel long distances, especially at night. However, it is generally more susceptible to static and interference compared to FM (Frequency Modulation) radio.

AM Radio stands for "Amplitude Modulation Radio." In AM radio, the amplitude (or strength) of the radio wave is varied in proportion to the waveform being sent, such as sound from a radio broadcast. This modulation technique allows AM radio to transmit audio signals over long distances.
Here’s a bit more detail:
- **Amplitude Modulation (AM):** This is a method of varying the strength of the carrier wave in accordance with the information signal. For AM radio, this means the audio signal (such as a radio broadcast) modulates the amplitude of a continuous wave signal.
- **Carrier Wave:** The carrier wave is a constant frequency signal that is modulated by the audio signal. In AM radio, this wave's amplitude changes to encode the audio information.
- **Frequency Range:** AM radio typically operates in the Medium Frequency (MF) band, which ranges from 530 kHz to 1700 kHz in most regions.
AM radio is known for its long-range capabilities, but it can be more susceptible to interference from electrical equipment and weather conditions compared to FM (Frequency Modulation) radio.
