Question

A sound wave of frequency 8000 Hz travels
with a speed of 340 m/s in air. Find its
wavelength
(Ans. 4.25 x 10-2 m)​

Answer 1

Answer:

Given,

Velocity V=340m/s

Wavelength λ=2cm=0.02m

Frequency f=?

We have,

V=F.λ

⇒340=F×0.02

F=0.02340=17,000Hz

As the audible range is in between 20Hz and 20,000Hz this sound wave is at audible range
