Physics - Wave on String Question with Solution | TestHub

A string on a musical instrument is held under tension T and extends from the point $\mathrm{x}=0$ to point $\mathrm{x}=\mathrm{L}$. The string is overwound with a wire in such a way that its mass per unit length $\mu (\mathrm{x})$ increases uniformly from ${\mu }_0$ at $\mathrm{x}=0$ to ${\mu }_{\mathrm{L}}$ at $\mathrm{x}=\mathrm{L}$. Find the time interval required for a transverse pulse to travel the length of the string.
