Question

The speed of sound in air is 322.7 m/s. What is the frequency of a soundwave that has a wavelength of 3.66 m?

Answer 1

In order to calculate the frequency of the wave, we can use the formula below:

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

Where v is the speed and lambda is the wavelength of the wave.

So we have:

$f=\frac{322.7}{3.66}=88.17\text{ Hz}$

Therefore the frequency is 88.17 Hz.
