If in an experiment for determination of velocity of sound by resonance tube method using a tuning fork of $$512$$ Hz, first resonance was observed at $$30.7$$ cm and second was obtained at $$63.2$$ cm, then maximum possible error in velocity of sound is (consider$$ actual speed of sound in air is $$332$$ $$m/s)

Question

Infinity Learn · Accepted Answer

Using  λ$$=2(l2$$−$$l1)$$⇒$$v=2n(l2$$−$$l1)$$⇒$$2$$×$$512(63.2$$−$$30.7)=33280cm/sActual$$ speed of sound  ⇒$$2$$×$$512(63.2$$−$$30.7)=33280cm/sHence$$ error $$=33280$$−$$33200=80cm/s$$
