A) \[1:2\]
B) \[4:1\]
C) \[1:4\]
D) \[2:1\]
Correct Answer: A
Solution :
Frequency of fundamental note in closed pipe is \[n'=\frac{v}{4l}\] ... (i) Frequency of fundamental note in open pipe is \[n'\,\,'=\frac{v}{2{{l}_{2}}}\] ... (ii) Given, \[n'=n'\,\,'\] \[\therefore \] \[\frac{v}{4{{l}_{1}}}=\frac{v}{2{{l}_{2}}}\] Note: A closed pipe produces only odd harmonics while an open pipe produces both even and odd harmonics.You need to login to perform this action.
