The fundamental frequency of an open pipe is N Keeping the pipe vertical, it is submerged in water such that half of it is immersed in water, so fundamental frequency of air column is :

Options

A. N
B. N/2
C. 2N
D. 3 N/4 .

Answer

A

Explanation

For open orgam pipe fundamentle frequency
`v_(0) = (V)/(2L)` = N
for closed pipe
` v_(c) = (V)/(4 ((L)/(2)) ) = (V)/(2L) = N `
`therefore` correct choice is (a) .
