If the initial tension on a stretched string is doubled, then the ratio of the initial and final speed of a transverse wave along the string is :Speed of a transverse wave on a string: $v = \sqrt{\frac{T}{\mu}} \propto \sqrt{T}$ $\frac{v_i}{v_f} = \sqrt{\frac{T_i}{T_f}} = \sqrt{\frac{T}{2T}} = \frac{1}{\sqrt{2}}$ So $v_i : v_f = 1 : \sqrt{2}$
