Question

A source of sound produces waves of wavelength 0.80 m in air. The same source of sound produces waves of wavelength 4.0 m in water. If the velocity of sound in air = 332 ms-1. Find the velocity of sound in water​

Answer 1

Answer:

1411ms-¹

Explanation:

The applicable expression is

v=nλ

where v is velocity of sound,n and λ are the frequency and wavelength of sound.

Using the given quantities for air 332=n×2

⇒n=3322=166Hz

For watervwater=n×λwater

⇒vwater

=166×8.5 (convert wavelength in to meters)

⇒vwater

=166×8.5

=1411ms-1
