Physics - Wave on String Question with Solution | TestHub

A stationary wave is represented by $\mathrm{y}=10\sin \frac{\pi \mathrm{x}}{4}\cos 20\pi \mathrm{t}$ where ' $\mathrm{x}$ ' and ' $\mathrm{y}$ ' are expressed in $\mathrm{cm}$ and ${}^{\prime }{t}^{\prime }$ in second. Distance between two consecutive nodes is
