    If the length of an open organ pipe is 33.3cm, then the frequency of fifth overtone is: (\[{{\operatorname{V}}_{sound}}\]=333m/s)

    A) 3000Hz                        

    B) 1500Hz

    C) 2500Hz                        

    D) 1250Hz

    Correct Answer: A

    Solution :

    \[\operatorname{Frequency} of {{5}^{th}} O.T = \left( 5 +1 \right) \frac{v}{2L}\] \[\operatorname{f}=\frac{6\times 333}{2\times 33.3\times 1{{0}^{-2}}}\]
