Question 3
Calculate the wavelength of a sound wave whose frequency is 220 Hz and speed is 440 m/s in a given medium.

Answer 1

Frequency of the sound wave, $v=220Hz$
Speed of the sound wave, $V=440m{s}^{-1}$
For a sound wave,
$Speed=Wavelength\times Frequency=\lambda \times v$
$\therefore \lambda =\frac{440}{220}=2m$
Hence, the wavelength of the sound wave is 2 m.
