Parts of a Wave
There are many parts of a wave. First, the crest is the highest point the medium rises to. Then, the wave length. The wave length is the distance between successive crests of a wave. After that, there's the amplitude. The amplitude is the distance from the rest position to the crest position. And lastly, is the wave trough and the wave trough the lowest point the medium sinks to.
Ocean Waves and Tsunamis
Waves are created by wind. Wind energy is transferred onto the water. The water doesn't move with the wind.
Tsunamis are created by quick movements on the ocean floor. They are usually earthquakes but they can be volcanic eruptions.
Tsunami is a Japanese word used as the scientific term for seismic sea wave, or a series of large ocean wave with extremely long wavelengths and long period.
Waves are a liquid body, as the sea or a lake, in the form of a moving ridge or swell.
Affects Things Have on Waves
Wave height is affected by wind speed and wind duration, If wind speed is slow, only small waves result, regardless of wind duration
Though, the wave length affects frequency in an inverse manner.
