Answer:

13 Hz

Step-by-step explanation:

The frequency of a wave is given by the equation:


f=(v)/(\lambda)

where

f is the frequency

v is the speed of the wave


\lambda is the wavelength

In this problem, we have:

v = 5.2 m/s is the speed of the wave


\lambda=0.40 m is the wavelength (distance between two adjacent crests)

Substituting into the formula, we find the frequency of the wave:


f=(5.2 m/s)/(0.40 m)=13 Hz
