Question

A sound wave travels at a speed of 339 metre per second if its wavelength is 1.5 cm what is the frequency of the wave will it audible

Answer 1

mate ,here is the solution,

velocity of the sound wave,v =339m/s
It's wavelength=1.5m=0.015m
we know that,
v=frequency*wavelength
339=frequency*0.015
This implies,
frequency=339/0.015=22600 Hz

So ,this sound is not audible,because the audible range for humans is ranges to 20Hz to 20000Hz,

Thanks for questioning..
