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

Numerical

Frequency of the sound wave, v = 220 Hz

Speed of the sound wave, v = 440 m s⁻¹

For a sound wave,

Speed = Wavelength × Frequency

v = `lamda xx nu`

∴ `lamda` = `"v"/nu`

= `440/220`

= 2 m

Hence, the wavelength of the sound wave is 2 m.
