(Definition of âhowdyâ from the Cambridge Academic Content Dictionary Â© Cambridge University Press)
A wave is an up and down movement of water. When we talk about waves, we use special words to name their parts. The highest point of a wave is called the crest. The lowest point is called the trough. Wave height is the vertical distance between the crest and trough. Wavelength is the horizontal distance between waves in a series. Wavelength can be measured between two wave crests. It can be measured between two wave troughs.
Aside from water and energy, the two main parts of a wave are its CREST, the area that is farthest from the Earth's core, and its TROUGH, the part of the wave that forms just â¦ before it gives way to the next crest. When two or more waves combine, their energies are combined.
