When two part of progressive ray trains of similar type having the same amplitude and similar time period/ wavelength/ frequency traveling with similar velocity along the similar straight line in reverse directions superimpose, a new set of rays are produced. These are called as stationary waves or standing waves.
The frequency of a wave is 50 Hertz and its wavelength is 25 meters. What is the velocity of this wave? Ans: The velocity of given wave is 1250 meters/second.
