wave amplitude

Wave amplitude refers to the maximum height of a wave from its resting or equilibrium position. It indicates the energy or intensity of the wave; higher amplitude means a more powerful wave. For example, in sound waves, greater amplitude results in louder sounds, while in water waves, larger amplitude corresponds to bigger, taller waves. Amplitude does not affect the wave's speed or frequency but is a key factor in how strong or impactful the wave is when it interacts with its environment.
