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

The correct option is D

0.50 m

For closed pipe $n_1=\frac{v}{4l}\Rightarrow l=\frac{v}{4n}=\frac{332}{4\times 166}=0.5m$
