Question

A sound wave travels at a speed of 339 m s-1. If its wavelength is 1.5 cm, what is the frequency of the wave? Will it be audible?​

Answer 1

Answer:

Step-by-step explanation:

Velocity of sound wave  u⇒339 ms−1

Wavelength of the waves λ⇒ 1.5 cm

                                              ⇒0.015 m

We know that    

∴ Frequency of the wave  v ⇒u/λ

                                                    ⇒339/0.015

                                                        ⇒22.6 KHZ

Audible frequency range for human ear lies between  20  Hz  to  20  kHz

Thus this waves is not audible
