Physics - Wave on String Question with Solution | TestHub

The ends of a stretched wire of length$L$are fixed at$x=0$and$x=L$. In one experiment the displacement of the wire is$y_1=\text{A }\text{sin}\left(\frac{\pi x}{\text{L}}\right)\text{ sin }\omega t$and energy is$E_1$and in other experiment its displacement is$y_2=\text{A }\text{sin}\left(\frac{\mathrm{2\pi }x}{\text{L}}\right)\text{ sin }\mathrm{2\omega }t$and energy is$E_2$. Then
