PhysicsEasysingle choice

The frequency of the first overtone of a closed pipe of length $l_{1}$ is equal to that of the first. overtone of an open pipe of length $l_{2}$ . The ratio of their lengths $(l_{1} : l_{2})$ is

Options:

Answer:

Solution:

Here, $v_{1} = \frac{( 2 n - 1 )}{4 l _{1}} v$ $v_{2} = \frac{n}{2 l _{2}} v$ Hence, $y_{1} = v_{2}$ $\frac{l _{1}}{l _{2}} = \frac{3}{4}$
