it depends on what you are talking about if your talking about light here it is light can be classified as a wave when your talking about crests and troughs a crest is the top most part of the wave if you split the wave in half the trough has the same principle it is the lowest most part of the wave if you split it in half does that clarrify a little bit?
The number of crests passing a particular point in one second is known to be the frequency. The distance covered by the wave will be the speed of the wave. Hence the distance covered for one vibration will be c / f
This distance is nothing but the distance between successive crests or troughs.
But wavelength = c/f
Hence wavelength = distance between successive crests or troughs.
Crests and troughs are parts of a wave. The crests are the points at which the amplitude is at its maximum, and the troughs are the points of minimum amplitude. Think of the crest of a hill, which is its peak. The troughs would then be the valleys between the hills.
In the graph of the equation y = sin(x), the crests of the sine wave are the points where y = 1, and the troughs are where y = -1.
Imagine a series of waves in the water. Top edge is crest, lowest part between waves is trough, distance between crests is wavelength.
well two parts of the wave are the crest (top) and the trough (bottom)
The peak-to-peak amplitude is the distance from the trough to the crest. The wavelength is the distance from one crest to the next crest.
Crest to trough
If it's crest to crest and trough to trough then it's the wavelength.
Measuring a wave from crest to trough in the verticaldirection will give the amplitude of the wave. It's called the peak to peak value (as it is is a measure of the distance from the positive peak to the negative peak -- the crest and trough). Measuring the wave in the horizontal direction from a crest to a trough will result in half a wavelength.Picture a water wave frozen on the surface of a pond. The distance (verticaly) from the bottom of a trough to the top of a crest is the amplitude of that wave. A measure of the distance (horizontally) from the bottom of a trough to the top of a crest is half the wavelength of the wave. (Note that athe use of "bottom of a trough" and "top of a crest" might seem redundant or even nonsensical, but is applied here in the hopes of clarity.)
The highest parts of a transverse wave are CRESTS.
Crest and Trough Amplitude Wavelength Frequency
From crest to crest, trough to trough or rest position to rest position
From crest to crest or trough to trough
From crest to crest or trough to trough
Is the wave length
wavelength
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.).
The distance from a crest to a crest or a trough to a trough in a wave.

it has to do with waves. trough- is the bottom of the wave crest- is the top of the wave
Usually it is shown in diagrams as from where the variable passes across the zero line, but your way will give the same result. It is the length of one complete cycle that matters.
The two main parts of a wave are the crest and the trough. The crest is the high part of the wave and the trough is the bottom.
