Physics - Wave on String Question with Solution | TestHub

A sonometer wire stretched by weight ' $w$ ' is in unison with a tuning fork. The corresponding resonating length is ' ${\mathrm{L}}_1$ ' if the weight is increased by ' $3w$ ' the corresponding resonating length of the sonometer in unison tuning fork becomes ' ${\mathrm{L}}_2$.' . The ratio $\left(\frac{{\mathrm{L}}_1}{{\mathrm{L}}_2}\right)$ is
