Q. The first overtone in a closed pipe has a frequency
A) Same as the fundamental frequency of an open tube of same length
B) Twice the fundamental frequency of an open tube of same length
C) Same as that of the first overtone of an open tube of same length
D) None of the above
Explanation
(d) First overtone for closed pipe $= \frac{3v}{4l}$
Fundamental frequency for open pipe $= \frac{v}{2l}$
First overtone for open pipe $= \frac{2v}{2l}$
