Detailed Solution

Concept- The frequency of the wave is 22.6 kHz. We will utilise the relationship between wavelength, frequency, and velocity to determine the frequency. We already know that frequency is proportional to wavelength. We shall substitute wavelength and velocity in connection to obtain the frequency of the sound wave in this question. Then, to determine whether it is audible, we will look at the hearing range of the human ear.
Velocity of sound wave

Wavelength of the waves

Frequency of the waves

Audible frequency range for human ear lies between

to

Thus this waves is not audible.
Hence, the answer is 22.6kHz.
