Water waves in the sea are observed to have a wavelength of m and a frequency of 0. The speed of these waves is:. E none of these. Sinusoidal water waves are generated in a large ripple tank. The time required for each new whole cycle to be generated is:.
A wave is a disturbance that moves along a medium from one end to the other. If one watches an ocean wave moving along the medium the ocean water , one can observe that the crest of the wave is moving from one location to another over a given interval of time. The crest is observed to cover distance. The speed of an object refers to how fast an object is moving and is usually expressed as the distance traveled per time of travel.
