A tuning fork is used to produce resonance in a glass tube. The length of the air column in this tube can be adjusted by a variable piston. At room temperature of $\displaystyle 27^{\circ} \mathrm{C}$ two successive resonances are produced at $\displaystyle 20$ cm and $\displaystyle 73$ cm of column length. If the frequency of the tuning fork is $\displaystyle 320$ Hz, the velocity of sound in air at $\displaystyle 27$°C is
Official answer
From NTA’s final answer key for this paper.
(2)
$\displaystyle 339$ m/s
