This calculator helps to determine the wavelength of a sound wave of particular frequency which is moving with a velocity v. Wavelength is nothing but the distance between two consecutive points in a wave. The formula for sound frequency is,

$\lambda$ = $\frac{v}{f}$

Where,$\lambda$ = wavelength of sound,

v = velocity of a sound wave,

f = frequency of sound wave.

**Step 1 :**Read the problem and note down the given measures.

**Step 2 :**Substitute these measures in the given formula,

$\lambda$ = $\frac{v}{f}$

and find out the unknown variable.

Let us discuss the problems related to wavelength of sound.

### Solved Examples

**Question 1:**Calculate the wavelength of sound which has a frequency 850Hz and traveling with a velocity of 340m/s.

**Solution:**

Given measures are,

f = 850Hz,

v = 340m/s

Wavelength of sound is,

$\lambda$ = $\frac{v}{f}$

$\lambda$ = $\frac{340}{850}$ = 0.4m

**Question 2:**The wavelength and velocity of a sound wave are 0.5m and 340m/s respectively. Calculate its frequency.

**Solution:**

Given measures are,

$\lambda$ = 0.5m,

v = 340m/s

Frequency of sound wave is,

$\lambda$ = $\frac{v}{f}$

f = $\frac{v}{\lambda}$

f = $\frac{340}{0.5}$

f = 680Hz
