A tuning fork of frequency 480 Hz is used in an experiment for measuring speed of sound (\upsilon ) in air by resonance tube method. Resonance is observed to occur at two successive lengths of the air column, l_{1}=30cm and l_{2}=70cm. Then, \upsilon is equal to:

 

  • Option 1)

    332 ms^{-1}

  • Option 2)

    384 ms^{-1}

  • Option 3)

    338 ms^{-1}

  • Option 4)

    379 ms^{-1}

S solutionqc

f=480 Hz   ,    \frac{\lambda }{2}=40cm ,         \lambda =80cm=0.8m

Vsound=f\lambda =480\times 0.8=384m/s

 


Option 1)

332 ms^{-1}

Option 2)

384 ms^{-1}

Option 3)

338 ms^{-1}

Option 4)

379 ms^{-1}
