    A resonance air column of length 40 cm resonates with a tuning fork of frequency 450 Hz. Ignoring end correction, the velocity of sound in air will be :

    A)  1020 m/s

    B)                         920 m/s              

    C)         820 m/s              

    D)         720 m/s

    Correct Answer: D

    Solution :

    Here : Length of column = 40 cm = 0.4m             Frequency of tuning fork = 450 Hz Using the formula \[n=\frac{v}{4l}\] or    \[v=450\times 4\times 0.4=720\,m\text{/}s\]
