Both the strings, shown in the figure are made of the same material and have the same cross-section. The pulleys are light. The wave speed of a transverse wave in the string $A B$ is $v_{1}$ and in the $C D$ it is $v_{2}$ . Then $\frac{v_{1}}{v_{2}}$ is

Options:

Answer:

Solution:

We know that $v = \sqrt{\frac{T}{μ}}$

Therefore $\frac{v_{1}}{v_{2}} = \sqrt{\frac{T_{1}}{T_{2}}}$

$\frac{v_{1}}{v_{2}} = \sqrt{\frac{T}{2 T}}$

$\frac{v_{1}}{v_{2}} = \frac{1}{\sqrt{2}}$
