The wavelength is the distance between the adjacent crest or trough of the sinusoidal wave. The wavelength is the reciprocal of the frequency of the wave.
Wavelength λ = 1/f
If a dog whistle has a frequency of 30000 Hz, then the wavelength will be
λ = 1/f
λ = 1/30000
λ = 3.33 x 10⁵ m
Thus, the wavelength of the sound of dog emitted is 3.33 x 10⁵ m
