The displacement of A particle at x = 0 of a stretched string carrying a wave in the positive x-direciion 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)`
