The displacement of A particle at x = 0 of a stretched string carrying a wave in the positive X-direction is given by f(t)=Ae^(-t^2). The wave speed is V. Write equation of the wave.

Answer»

`f(X,t) = AE^(-(t + x)^2)`
`f(x,t) = Ae^(-(t - x/v)^2)`
`f(x,t) = Ae^((t + x/v)^2)`
`f(x,t) = Ae^(-(t + x/v)^2)`
