Question
How can velocity of a wave be determined ?
Solution
The velocity of a wave can be determined as follows :
Every wave has a wave length, velocity, height and wave period. The distance between two successive crests or two successive troughs is called wave length. The time taken by a wave length to pass a fixed point is known as the wave period. The vertical distances between a trough and crest is the wave height.
