Question

explain formation of stationary waves

Answer 1

is a wave in a medium in which each point on the axis of the wave has an associated constant amplitude. The locations at which the amplitude is minimum are called nodes, and the locations where the amplitude is maximum are called antinodes

Answer 2

stationary waves is the result of interference
of the two wave pattern known as a standing wave pattern.Standing waves are produced whenever two waves to identical frequency interfere with one another while travelling opposite directions along the same medium......
