The amplitude of wave distance propagating in the positive X-direction is given by y = (1)/((1 + x)^(2)) at time t = 0 and y = (1)/(1 + (x - 1)^(2)) at t = 1 seconds here x and y are in metre. The shape of wave disturbance does not change during propagation. The velocity of wave is : |

Answer» `2 ms^(-1)` att = 0 SEC `"" y = (1)/(1 + x^(2))` Att = 2 sec. `"" y = (1)/(1 + (x - 2V)^(2)) ` comparing this with`y = (1)/(1 + (x - 1)^(2))` We have 2v = 1 `rArr "" v = 0.5 ms^(-1)`. correct CHOICE is d. |
