[40]What is the wavelength of the sound waves whose frequency is 220 Hz and speed 440 m/s?

2 m

is the wavelength of the sound waves whose frequency is

220 Hz

and speed

440 m / s

.
Given velocity of wave ,

V = 440 m / s

Frequency of wave ν = 220 Hz

We know that the relation between wavelength (

λ

) and frequency (

v)

of wave

\Rightarrow

V = νλ

\Rightarrow 440 m / s = 220 Hz \times λ

\Rightarrow

λ = 2 m

Hence the wavelength of the sound wave is

2 m
