Physics - Sound Wave Question with Solution | TestHub

A closed organ pipe of length $L$ and an open organ pipe contain gases of densities ${\rho }_1$ and ${\rho }_2$ respectively. The compressibility of gases are equal in both the pipes. Both the pipes are vibrating in their first overtone with same frequency. The length of the open pipe is $\frac{x}{3}L\sqrt{\frac{{\rho }_1}{{\rho }_2}}$, where $x$ is _______.
