* Amplitude: The amplitude of a wave is the maximum displacement of a point on the wave from its equilibrium position.
* Peak to Trough: The distance from the highest point (peak) of a wave to the lowest point (trough) represents the full range of the wave's displacement.
* Double the Amplitude: Since the amplitude is the distance from the equilibrium to the peak (or trough), the total distance from peak to trough is twice the amplitude.
Therefore, if the amplitude is 1 meter, the top to bottom distance (peak to trough) is 2 meters.
