Physics - Sound Wave Question with Solution | TestHub

The equation of a stationary wave in a metal rod is given by$y=0.002 \sin \frac{\pi x}{3} \sin 1000t$, where$x$is in$\mathrm{cm}$and$t$is in second. The maximum tensile stress at a point$x=1 \mathrm{cm}$is$\frac{n\pi }{3}\times 10^8 \mathrm{dyne} {\mathrm{cm}}^{-2}$. What is the value of$n$? [Young's modulus of the material of rod is =$8\times 10^{11} \mathrm{dyne} {\mathrm{cm}}^{-2}$]
