Question

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

Answer 1

Answer: (D)

0.50 m

Answer 2

For closed pipe

$n_{1} = \frac{v}{4l} \Rightarrow l = \frac{v}{4n} = \frac{332}{4 \times 166} = 0.5m$
