Question

20. Define standing wave. Displacement of a string in which standing wave is formed is given as
y = (20 sin 157xcos 314)
Find (a) Amplitude of individual waves (b) Velocity of wave.

​

Answer 1

Answer:

In physics, a standing wave, also known as a stationary wave, is a wave which oscillates in time but whose peak amplitude profile does not move in space. The peak amplitude of the wave oscillations at any point in space is constant with time, and the oscillations at different points throughout the wave are in phase
