Dogs are able to hear much higher frequencies than humans are capable of detecting. For this reason, dog whistles that are inaudible to the human ear can be heard easily by a dog. If a dog whistle has a frequency of 30000 Hz, what is the wavelength of the sound emitted? 



Answer :

Wavelength = 1/frequency thus wavelength =1/30000

The wavelength of the sound emitted is 3.33 x 10⁵ m.

What is wavelength?

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
