A) \[1:1\]
B) \[2:1\]
C) \[1:4\]
D) \[1:2\]
E) \[4:1\]
Correct Answer: D
Solution :
Fundamental frequency of closed pipe, \[{{n}_{1}}=\frac{v}{4{{l}_{1}}}\] Fundamental frequency of open pipe, \[{{n}_{2}}=\frac{v}{2{{l}_{2}}}\] But \[{{n}_{1}}={{n}_{2}}\] \[\therefore \] \[\frac{{{l}_{1}}}{{{l}_{2}}}=\frac{1}{2}\]You need to login to perform this action.
