Answer :
Speed (v) of sound = 339 m/s
Wavelength \( \lambda \) of sound = 1.5 cm = 0.015 m
We know that,
\( Speed \ of \ sound \ = \ Wavelength \ × \ Frequency \)
\( v \ = \ \lambda \ × \ \nu \)
\( v = \frac{v}{ \lambda } = \frac{339}{0.015} = 22600 \ Hz \) .
The frequency of audible sound for human beings lies between the ranges of 20 Hz to 20,000 Hz. The frequency of the given sound is more than 20,000 Hz, therefore, it is not audible.
