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

Solution
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=lambdaxxupsilon`
`thereforelambda=v/upsilon=440/220=2 m`
Hence, the wavelength of the sound wave is 2 m.
