(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.
A wave that appears to be standing still, produced by the interference of two traveling waves moving in opposite directions wave front A line representing the crest of a wave in two dimensions that can show the wavelength, but not the amplitude, of the wave when drawn to scale ray A line that can show the direction a wave is traveling and is drawn at a right angle to a wave's crest
