Question

What is the distance between condensation and perception if the sound wavelength is lambda?​

Answer 1

Answer:

Wavelength of sound waves in the first medium,

λ=νv                               .......(i)

Wavelength of sound waves in the second medium,

λ′=ν′2v                           ........(ii)

As the frequency of the wave remains unchanged with the change in medium 

∴ν=ν′                                 .........(iii)

Divide (ii) by (i), we get

λλ′=2

or λ′=2λ
