Q. The fundamental note produced by a closed organ pipe is of frequency $f.$ The fundamental note produced by an open organ pipe of same length will be of frequency
A) $f/2$
B) $f$
C) $2f$
D) $4f$
Explanation
(c) $n_{closed} = \frac{v}{4l},n_{open} = \frac{v}{2l} \Rightarrow n_{open} = 2n_{closed} = 2f$
