AM modulation changes the amplitude of the carrier wave, while FM modulation changes its frequency — and this simple difference is why FM sounds clearer and AM can travel farther.

This clip comes from a full video explaining how a radio transmitter works, from the carrier wave to modulation, amplification, and transmission.
