AM is also used to modulate light waves in optical fibers. See modulation and carrier. Vary the Amplitude In AM modulation, the voltage (amplitude) of the carrier is varied by the incoming signal.

Okay, what exactly is a modulation effect, anyway? Modulation effects are a broad group encompassing the likes of phaser, chorus, flanger, tremolo and vibrato pedals, plus other variations on the ...
