The term that describes the distance from the crest to the trough of a wave is called the amplitude.
it look the objects trough it..

That may refer to Dante's "Divine Comedy".
The wavelength of a wave describes the distance between two successive points of the same phase, such as crest to crest or trough to trough. It is a measure of the spatial extent of a wave pattern.
Light goes incredibly fast through space, bouncing off objects.
Trough
It is called trough. The highest point is known to be crest. The distance between successive crests is known as wavelength of the wave. This is the most important characteristic of a wave. Same way the distance between any two successive troughs too is the wavelength.
A trough is something that contains food or water. A small animal might be fed from a bowl; a large animal needs a bigger food container. That's a trough. A visual: you know how in movies set in the American West, after a fight, somebody ends up in the water container the horses were drinking out of? That's a water trough.
