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

**
Answer
**

Speed of sound = 440m/s

Frequency of sound = 220 Hz

We know that

Speed of sound = Wavelength x Frequency

Wavelength = Speed of sound/ Frequency

= 440/220

= 2 m

Wavelength is
