354901 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 \(27^\circ C\) two successive resonances are produced at \(20\;cm\) and \(73\;cm\) of column length. If the frequency of the tuning fork is \(320\;Hz\), the velocity of sound in air at \(27^\circ C\) is
