FM waves modulate the frequency of the wave and AM waves modulate the amplitude of the wave. Electrical noise is generally amplitude modulation, and will thus interfere with AM waves more than FM waves. Recall that FM is frequency modulation and AM is amplitude modulation. That’s where the FM and AM come from; they’re the appreviations for the modulation schemes.
