If you are referring to a sine wave, a crest is the point on a wave with the maximum value or upward displacement within a cycle. A trough is the opposite of a crest, so it is the minimum or lowest point in a cycle.

The amplitude is 1/2 the the difference between the crest and trough.
The wavelength of a wave is the distance between two identical parts of a wave in successive periods (crest to crest, trough to trough, etc.).
They are both part of a wave. The crest is at the top, and the trough is at the bottom.
From crest to crest, trough to trough or rest position to rest position
The distance between the crest and trough of a wave is the peak-to-peak amplitude of the wave.
The amplitude is 1/2 the the difference between the crest and trough.
The wavelength of a wave is the distance between two identical parts of a wave in successive periods (crest to crest, trough to trough, etc.).
Distance between a trough and crest in a wave is half wavelength
They are both part of a wave. The crest is at the top, and the trough is at the bottom.
The distance between the crest and trough of a wave is the peak-to-peak amplitude of the wave.
wave height. -- The highest point of a wave is known as its crest while the trough is the lowest point of the wave. Wavelength is the horizontal distance between successive crests or troughs. by: Claire O.

wavelength - distance between waves (eg crest to crest or trough to trough)
The distance between the crest and trough of a wave is the peak-to-peak amplitude of the wave.
From crest to crest or trough to trough
No, the distance from one wave crest to the next is notcalled a trough. That distance is called a wavelength. A trough is the lowest point of a wave.
