A) \[4\,m\]
B) \[2\,m\]
C) \[8\,m\]
D) \[1\,m\]
Correct Answer: A
Solution :
Second overtone of open pipe of length I is \[{{n}_{0}}=\frac{v}{2l}\] ??(i) First overtone of a closed pipe is \[{{n}_{c}}=\frac{v}{4l}=\frac{v}{4\times 2}\] ?..(ii) Equating Eqs. (i) and (ii), we get \[\frac{v}{2l}=\frac{v}{8}\] \[\Rightarrow \] \[l=4\,m\]You need to login to perform this action.
