Here's how:
* Amplitude is the maximum displacement of a point on a wave from its equilibrium position. It's essentially the "height" of the wave from its undisturbed state.
* Wave height is the vertical distance between the crest (highest point) and the trough (lowest point) of a wave.
Therefore:
* Wave height = 2 * Amplitude
In simpler terms, the wave height is twice the amplitude because it measures the total distance between the highest and lowest points, while the amplitude only measures the distance from the equilibrium point to either the crest or the trough.
