The displacement of the particle at x = 0 of a streached string carrying a wave in the positive x direction is given by f(t)= A sin `(t/T)`. The wave speed is V. Write the wave equation

Options

A. `f(x,t) = A sin(t/T -x/V)`
B. `f(x,t) = A sin (t/T + x/(VT))`
C. `f(x,t) = A sin(t + x/(VT))`
D. `f(x,t) = A sin(t/T - x/(VT))`

Answer

D
