In a resonance tube, using a tuning fork of frequency $325 Hz$ , two successive resonance length are observed as $25.4 cm$ and $77.4 cm$ respectively. The velocity of sound in air is

Options:

Answer:

Solution:

$v = 2 n (l_{2} - l_{1}) = 2 \times 325 (77.4 - 25.4) c m s^{- 1}$

$= \frac{650 \times 52}{100} m s^{- 1} = 338 m s^{- 1}$
