Answer :

Given that,

Frequency of sound wave = 220 Hz.

Speed of sound wave = 440 m/s.

Calculate wavelength.

We know that,

Speed = Wavelength × Frequency

\(\Rightarrow v = \lambda \nu \)

\(\Rightarrow 440 \ = \ Wavelength \ × \ 220 \)

\( \Rightarrow Wavelength \ = \ \frac{440}{220} \)

\(\therefore \) Wavelength = 2 m
