(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.
Each crest is followed by second crest which is again followed by next crest. These crests are separated by a trough to generate a pattern of crests and troughs. In physics, waves are defined as periodical disturbance which are propagated through a particular medium.
