Is AM or FM Better?

In FM, a radio wave known as the "carrier" or "carrier wave" is modulated in frequency by the signal that is to be transmitted. FM is less prone to interference than AM. However, FM signals are impacted by physical barriers. FM has better sound quality due to higher bandwidth.

Hereof, what is AM radio mean?

AM stands for amplitude modulation, which means the amplitude of the radio signal is used to encode information. FM denotes frequency modulation, which uses a change in frequency to encode information.

What is AM radio frequency?

The Amplitude Modulated (AM radio) carrier frequencies are in the frequency range 535-1605 kHz. Carrier frequencies of 540 to 1600 kHz are assigned at 10 kHz intervals. The FM radio band is from 88 to 108 MHz between VHF television Channels 6 and 7.

Why do AM waves travel farther than FM?

Low frequencies travel farther mostly because they propagate along the surface of the earth. High frequency FM signals are basically line of sight. Under the right conditions, AM signals will bounce off of the ionosphere and can travel around the globe. This is not possible with high frequency signals.
