Crest = top of wave Wave trough = lowest point between each crest Wave height = distance between crest and trough Wavelength = distance from crest to crest or trough to trough.

A “roll cloud” spotted off the coast of Portugal looked like something out of a movie. Here’s the science behind it.

If the opposite occurs and one wave's crest overlaps the other's trough, the waves cancel out each other. This is known as destructive interference. Adding Sine Waves ...

The hand could be thrust into the sand without excessive resistance to a depth of about 7.5 cm on the crest of the ripple and 5 cm in the trough, indicating unconsolidated conditions to these depths.

"Crest to trough", plus characteristics of shape, heaviness etc., works for me, because it allows thinking about the relationship between the board design and the wave, in a way that "behind the ...

After the crest, the first 150 meters (500 feet) of the flat mitigates half of the wave’s remaining energy. The reef’s ability to dampen waves also depends on two physical qualities: height ...
