At t=0, a transverse wave pulse in a wire is described by the function `y=6//(x^(2)-3)` where x and y are in metres. The function y(x,t) that describes this wave equation if it is travelling in the positive x direction with a speed of `4.5 m//s` isA. `y=(6)/((x+4.5t)^(3)-3)`B. `y = (6)/((x-4.5 t^(2))+3)`C. `y = (6)/((x+4.5 t)^(2)-3)`D. `y = (6)/((x-4.5 t)^(2)-3)` |

Answer» Correct Answer - C `y (x, t)=(a)/((x pm vt)^(2)+b)` is another form of progressive wave equation propagating with a speed v. Negative sign to be taken for propagation along + x-axis and positive sign to be taken for propagation along - x-axis. |
