In a resonance tube experiment, to determine the speed of sound in air, a pipe of diameter $5 \mathrm{cm}$ is used. The air column in the pipe resonates with a tuning fork of frequency $480 \mathrm{Hz}$ when the minimum length of the air column is $16 \mathrm{cm}$. Find the speed of sound ( in $\mathrm{m} {\mathrm{s}}^{-1}$ ) in the air at room temperature.
