The height of a transverse wave from the midpoint to the crest or trough is the amplitude

Explanation:

The waves are usually represented by amplitude and the frequency. Amplitude is used to represent the energy as the wave propagates or travels through a medium whereas frequency is related to the time as the number of cycles per second. Trough is used to define the lowest point in the wave and the peak point is called as crest.
