Question

If a radio wave carries information by changing the amplitude of the transmitted wave, what kind of broadcast might it possibly be?.

Answer 1

An AM radio broadcast uses amplitude modulation to encode information into a radio wave by varying the amplitude while keeping the frequency constant, typically within the 540 to 1600 kHz range.

Step-by-step explanation:

If a radio wave carries information by changing the amplitude of the transmitted wave, it could possibly be an AM radio broadcast. AM, which stands for amplitude modulation, is a broadcasting method where information is encoded into a carrier wave by varying its amplitude. In this process, the frequency of the carrier wave remains constant, while the amplitude is modulated in accordance with the audio signal. Commercial AM radio signals are typically found in the frequency range from 540 to 1600 kHz. The modulated wave effectively superimposes an audio signal onto the consistent frequency of the carrier wave, allowing information to be conveyed over long distances.

Answer 2

AM (Amplitude Modulation)

Step-by-step explanation:

In AM broadcasting, the amplitude of the radio wave is changed to match the audio signal being transmitted. By modifying the amplitude, the audio signal is combined with a carrier wave, resulting in a modulated wave that carries the audio information.
