# Calculate the wavelength of a sound wave whose frequency is 220 Hz and speed is 440 m/s in a given medium.

Answers (1)

Given a sound wave whose frequency is $220Hz$ and speed is $440\ m/s$, then its wavelength will be:

As velocity is given by,

$v = \lambda\times \nu$

Then $\lambda = \frac{v}{\nu}$

Or, $\lambda = \frac{440\ m/s}{220\ Hz} = 2\ m$.

Thus, the wavelength of the given sound wave is 2m.
