Question

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

Answer:

336.00

Solution:

$\frac{v}{4 [L + 0.6 r]} = 480$

$⇒ v = 480 \times 4 \times [L + 0.6 r]$

$\Rightarrow v = 336 m s^{- 1}$

v 4 L + 0 . 6 r = 4 8 0 ⇒ v = 480 × 4 × [ L + 0 . 6 r ] ⇒ v = 336 m s - 1
