Q. The frequency of fundamental tone in an open organ pipe of length $0.48\ m$ is $320\ Hz.$ Speed of sound is $320\ m/sec.$ Frequency of fundamental tone in closed organ pipe will be
A) $153.8\ Hz$
B) $160.0\ Hz$
C) $320.0\ Hz$
D) $143.2\ Hz$
Explanation
(b) $n_{Closed} = \frac{1}{2}\left( n_{Open} \right) = \frac{1}{2} \times 320 = 160\ Hz$
