"WebYou accurately stated that FM needs to vary more by nature of the signal transfer. As such, they need a much wider bandwidth than AM. Generally, they are transmitted at higher frequencies (88 MHz to 108 or so) where as AM tends to be in the kHz range, with much narrower gaps. So, technically, you are both correct.
