The wavelength of the sound wave in given medium is $2 m$

#### Explanation:

$v = f \lambda$

Where $v$ is speed in given medium= $440 m {s}^{-} 1$,
$f$ is frequency in given medium= $220 H z$, and
$\lambda$ is wavelength in metres = $\lambda = \frac{v}{f}$

$\implies \lambda = \frac{440}{220} = 2 m e t e r s$

$\therefore$ The wavelength of the sound wave in given medium is $2 m$
