Hey mate Here your answer

Sound wave speed=340 m/s
Wavelength=2 cm=0.02 metres
Frequency=????

Formula
Velocity=Frequency×wavelength
Frequency×0.02=340
Frequency=340/0.02
Frequency=17000 Hertz

As Audible range=20 Hertz to 20000 Hertz

So it is in Audible range

As when you divide 340÷0.02 you will get=17000 hertz
