Question

time period of oscillation of a particle in a sound wave is 10 Milliseconds if speed of sound is 340 m per second then find the wavelength?​

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=

0.02

340

=17,000Hz

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