The disturbance travels with a velocity v. The time for one complete cycle
is T. Thus, since:

It takes time for the motion of one atom or molecule to affect the next atom or molecule. This means that the original disturbance in the medium takes
The velocity of a wave is the speed of the disturbance as it passes through the medium – not the velocity of the particles within the medium.
