Two strings with circular cross section and made of same material, are stretched to have same amount of tension. A transverse wave is then made to pass through both the strings. The velocity of the wave in the first string having the radius of cross section R is $\displaystyle v_1$, and that in the other string having radius of cross section $\displaystyle \mathrm{R} / 2$ is $\displaystyle v_2$. Then $\displaystyle \frac{v_2}{v_1}=$
