The amplitude of a wave disturbance propagating along positive x - axis is given by \[y=\frac{1}{(1+{{x}^{2}})}\] at t = 0 and \[y=\frac{1}{1+{{(x-2)}^{2}}}\] at \[t=4\text{ }s\], where x and y are in metre. The shape of wave disturbance does not change with time. Find velocity (in m/s) of the wave.
