A) 1 : 2
B) 2 : 1
C) 2 : 3
D) 4 : 3
Correct Answer: A
Solution :
[a] For closed organ pipe \[\frac{\lambda }{4}=\ell \]\[\Rightarrow \]\[\lambda =4\ell ;\] \[n=\frac{v}{\lambda }=\frac{v}{4\ell }\] For open organ pipe, \[\frac{\lambda }{2}=\ell \] \[\Rightarrow \] \[\lambda =2\ell ;\] \[n'=\frac{v}{\lambda }=\frac{v}{2\ell }\] \[n'=2n;\] \[n:n'=1:2\]You need to login to perform this action.
