Question

The range of the wavelength of audible sound that travels with a velocity of $330m{s}^{-1}$ at $0^{o}C$ is ________.

Answer 1

$16.5\times {10}^{-3}metres$ to $16.5metres$

Audible sound falls in the frequency range of $20Hz$ to $20\times {10}^{3}Hz$

Wavelength $\lambda$ in metres is given by $\frac{velocity\left(v\right)}{Frequency\left(n\right)}$

Where $v$ is in $m/s$ and $n$ is in $Hz$

Hence the range of the wavelength of audible sound that travels with a velocity of 330m/s will be given by

$\frac{330}{20\times {10}^3}$metres to $\frac{330}{20}$metres

That is = $16.5\times {10}^{-3}metres$ to $16.5metres$
