If at t = 0, a travelling wave pulse in ...

If at `t = 0`, a travelling wave pulse in a string is described by the function,
`y = (10)/((x^(2) + 2 ))`
Hence, `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 positive x-axis with speed `2 m//s`?

A

`y=10/((x^(2)+ 2y)^(2) +2)`

B

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

C

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

D

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