The ratio of frequencies of fundamental harmonic produced by an open pipe to that of a closed pipe having the same length is:

A $1 : 2$
B $2 : 1$
C $1 : 3$
D $3 : 1$

Solution & Step-by-step Explanation

Fundamental frequency of an open pipe (f_{o p e n}) = \frac{v}{2 L} Fundamental frequency of a closed pipe (f_{c l ose d}) = \frac{v}{4 L} Ratio: \frac{f _{o p e n}}{f _{c l ose d}} = \frac{v /2 L}{v /4 L} = \frac{4}{2} = \frac{2}{1} The ratio is 2 : 1 .
