Quest: Calculate the wavelength of a sound wave whose frequency is 220 Hz and speed is 440 m/s in a given medium.
Solution:9. Frequency of the sound wave, Î½= 220 Hz
Speed of the sound wave, v = 440 m s-1
For a sound wave,
Speed = Wavelength x Frequencyv = Î» x Î½
ˆ´ Î»= v / Î½ = 440 / 220 = 2m
Hence, the wavelength of the sound wave is 2 m.
