Answer the following question given this paragraph: 

In a transverse wave, particles of the medium move up and down at right angles to the direction of the wave. Wave amplitude of a transverse wave is the difference in height between the crest and the resting position. The crest is the highest point particles of the medium reach. The higher the crests are, the greater the amplitude of the wave.


Q: In a transverse wave, the highest point the wave reaches is known as the?


A:
crest
