What is amplitude

Answer
Amplitude is the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It represents the intensity or magnitude of a wave or oscillation.
For example, in a sound wave, amplitude corresponds to the loudness of the sound. In a light wave, it relates to the brightness of the light. For a simple harmonic motion, like a pendulum swinging, the amplitude is the maximum angle or distance the pendulum swings away from its resting point.
