Q. An air column in a pipe, which is closed at one end, will be in resonance with a vibrating body of frequency $166\ Hz,$ if the length of the air column is
A) $2.00\ m$
B) $1.50\ m$
C) $1.00\ m$
D) $0.50\ m$
Explanation
(d) For closed pipe $n_{1} = \frac{v}{4l} \Rightarrow l = \frac{v}{4n} = \frac{332}{4 \times 166} = 0.5m$
