    If the velocity of sound in air is\[350\,\,m/s\], then fundamental frequency of an open organ pipe of length \[50\,\,cm\] is

    A) \[980\,\,Hz\]                     

    B) \[700\,\,Hz\]

    C) \[350\,\,Hz\]                     

    D) \[175\,\,Hz\]

    Correct Answer: C

    Solution :

    Velocity of sound in air\[v=350\,\,m/s\] Length of organ pipe\[l=50\,\,cm=0.5\,\,m\] The fundamental frequency of an open organ pipe is given by                 \[n=\frac{v}{2l}=\frac{350}{2\times 0.5}=350\,\,Hz\]
