Answer:

$\Huge{\bold{20 Hz}}$

Step-by-step explanation:

The frequency of the wave given it's velocity and wavelength can be found by using the formula

$frequency = (v)/( \lambda)$

where
$\lambda$ is the wavelength

From the question

v = 500 m/s

$\lambda$ = 25 m

We have

$f = (500)/(25) = 20 \\$

We have the final answer as
