A sound wave travels at a speed of 340 m/s. If its wavelength is 1.5 cm. What is the frequency of the wave? Will it be audible?

Given that, speed of sound, v = 340 m/s

Wavelength, $\lambda $ = 1.5 cm = 1.5/100 m.-Frequency, V = ?

Using the formulae , v = V$\lambda $

V = v / $\lambda $ = 340 / (1.5/100) = 340 x 100/1.5 = 22666.6 Hz

We know that, audible range of frequencies is 20 Hz to 20000 Hz.

So, the given frequency (i.e. 22666.6 Hz) is not audible.
