    The maximum magnitude of displacement, so this amount right here, whatever that distance is here, is called the amplitude. So we represent the amplitude with a capital A, and it's called the amplitude, and it's defined to be the maximum magnitude of displacement for that oscillator.

    It we turn up the volume, we see that the oscillations become larger, and the sound becomes louder. The maximum displacement of the air molecule from its undisturbed position is called the amplitude. Be careful. The amplitude is not the length of the entire displacement. It's only the maximum displacement measured from the equilibrium position.
