(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.
Wave height. The vertical distance between the highest (crest) and lowest (trough) parts of a wave. Wavelength. The distance from a certain point on one wave to the same point on the next wave (e.g. distance between two consecutive wave crests or between two consecutive wave troughs). Wave amplitude. One half the distance from the crest to the trough.
