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

The frequency of the sound wave, n= 220 Hz

Speed of the sound wave, v = 440 m/s

For a sound wave,

Speed = Wavelength x Frequency

v = λ × n

440 = λ × 220

λ = 440/220 = 2 m

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