Physics - Wave on String Question with Solution | TestHub

The displacement $y$ of a wave travelling in the $x$-direction is given by $y=10^{-4}\sin \left(600t-2x+\frac{\pi }{3}\right)$ metres where $\mathrm{x}$ is expressed in metres and $\mathrm{t}$ in seconds. The speed of the wave-motion, in ${\mathrm{ms}}^{-1}$, is
