A dog whistle is designed to produce a sound with a frequency beyond that which can be heard by humans (between 20,000 Hz and 27

,000 Hz). If a particular whistle produces a sound with a frequency of 25,000 Hz, what is the sound’s speed? Assume the wavelength of this sound wave in air is 0.013m. *

Answer:

Speed of the sound in air is 325 m/s

Explanation:

As we know that the frequency of the sound is given as

f = 25000 Hz

wavelength of the sound is given as

\lambda = 0.013 m

now we have

v = \lambda f

so we have

v = (0.013)(25000)

v = 325 m/s
