Correct Answer: C
Solution :
First overtone of closed organ pipe\[{{n}_{1}}=\frac{3v}{4{{l}_{1}}}\] Third overtone of open organ pipe\[{{n}_{2}}=\frac{4v}{2{{l}_{2}}}\] \[{{n}_{1}}={{n}_{2}}\](given) \[\Rightarrow \] \[\frac{3v}{4{{l}_{1}}}=\frac{4v}{2{{l}_{2}}}\] \[\frac{{{l}_{1}}}{{{l}_{2}}}=\frac{3}{8}\]You need to login to perform this action.
