A sound wave travels at a speed of 339 m/s. If its wavelength is 1.5 cm, what is the frequency of the wave? Will it be audible?

Given,

Speed of sound, v = 339 m/s

Wavelength of sound, $\lambda =1.5 cm =0.015 m$

Speed of sound = Wavelength x Frequency

                               $v =\lambda \times \vartheta$

Substituting the values,

$339 =0.015 \times \vartheta$

$\vartheta = 22600 Hz$

The audible frequency range of humans lies between $20 Hz$ to $20,000 Hz$ . Since the frequency of the given sound is more than $20,000 Hz$ , it won’t be audible.
