Question

Numerical problems:

The velocity of sound in air is 344 ms^-1 What is the range of wavelength of audible sound?

Answer 1

Velocity of sound in air, v = 344 ms^-1
Audible frequency range = 20 – 20,000 Hz
We know V = vλ⇒λ=`"v"/"v"`
When Fequency v = 20Hz
λ=`344/20`=17.2m
When Frequency, v = 20,000Hz
λ=`344/20,000`=0.0172m
Range of wavelength of audible Sound = 0.0172 m- 17.2 m
