Question

what is formula for speed wave . what does f and A symbols represent and what unit is speed wave measured in

Answer 1

$\begin{gathered} v=Aw\sin (kx-wt) \\ \text{but} \\ w=2\pi f \\ \text{Hence} \\ v=2\pi fA\sin (kx-2\pi ft) \\ A=\text{amplitude} \\ f=frequency \\ \text{The unit of the sp}eed\text{ is } \end{gathered}$
