Physics - Wave on String Question with Solution | TestHub

In a wave, travelling in +X direction with speed of 2cm/s, the particles displacement at $\mathrm{x}=0$ is given by $\mathrm{y}(\mathrm{mm})=\{\begin{array}{ll}2\mathrm{t}& 0⩽\mathrm{t}⩽2\\ 6-\mathrm{t}& 2<\mathrm{t}⩽4\end{array}$. Find the displacement of particle (in mm) at $\mathrm{x}=4\mathrm{cm}$ at $\mathrm{t}=5\sec$.
