# Calculate the wavelength of a sound wave whose frequency is 220 Hz and speed is 440 m/s in a given medium.

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
