Answer:

$2.5\cdot 10^6 Hz$

Step-by-step explanation:

The relationship between the speed of a wave, its frequency and its wavelength is given by the wave equation:

$v=f\lambda$

where

v is the wave speed

f is the frequency of the wave, which is the number of cycles completed by the wave in one oscillation

$\lambda$ is the wavelength, which is the distance between two consecutive crests of the wave

For the wave in this problem we have:

v = 5000 m/s is the speed

$\lambda=0.002 m$ is the wavelength of the wave

Solving for f, we find the frequency:

$f=(v)/(\lambda)=(5000)/(0.002)=2.5\cdot 10^6 Hz$
