In closed organ pipe at one end-

Options

A. A-T,B-P,C-P,D-T
B. A-S,B-P,C-P,D-(Q,T)
C. A-S,B_Q,C-R,D-Q
D. A-R,B_Q,C-S,D-(Q,T)

Answer

B

Explanation

For (A) in column (I):
third overtone frequency `=7f_(0)`
`therefore x=7`
for (B) in column (I):
Second overtone =5`f_(0)`
`therefore`No of nodes=3
For (C) in column (I)
Second overtone=5`f_(0)`
No of antinode=3
For (D) in column-I
In closed organ pipe even harmonics does not exist.
So, n=2,4,6, . ..
