“A wave is a disturbance produced in a medium which propagates with a definite speed without  making any change in the  medium”.  When a wave propagates the particles of the medium oscillates at their own position with frequency and amplitude that of the wave. During oscillation the particles transfer energy to the next particles of … Read more
