At t = 0 a travelling wave pulse on a string is described by the function y=10/(x^(2) +2) , here x and y are in meter and t in second, What will be the wave function representing the pulse at time t. if the pulse is propagating along ihe positive x-axis with .speed 2m/s .?

Answer»

`y=10/((x^(2)+ 2Y)^(2) +2)`
`y=10/((x^(2) + 2T)^(2) +2)`
`y=10/((x-2t)^(2)+ 2)`
`y=10/((x+2t)^(2) + 2)`
