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.

Correct answer

336

Step-by-step solution

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