How is the infrastructure at Waves Institute? What are the facilities available for students?

The amplitude of wave disturbance propagating in the positive x-direction is given by   $y=\frac{1}{1+{\left(x\right)}^2}$ at time t = 0 and $y=\frac{1}{1+{\left(x-2\right)}^2}$  at t = 1s, where x and y are in metres. The shape of wave does not change during the propagation. The velocity of the wave will be_______ m/s.
