Question

The amplitude of wave disturbance propagating in the positive x-direction is given by y= 11+x^2 at time t=0 and y= 11+(x-2)^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

Accepted Answer

Correct answer: 2. (2) At t=0 ,y= 11+x^2 At time t=t ,y= 11+(x- vt)^2 At t=1 ,y= 11+(x-v)^2….(i) At t=1 ,y= 11+(x-2)^2 …(ii) Comparing (i) & (ii) V=2m/s

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