Answer:
13 Hz
Explanation:
The frequency of a wave is given by the equation:
[tex]f=\frac{v}{\lambda}[/tex]
where
f is the frequency
v is the speed of the wave
[tex]\lambda[/tex] is the wavelength
In this problem, we have:
v = 5.2 m/s is the speed of the wave
[tex]\lambda=0.40 m[/tex] is the wavelength (distance between two adjacent crests)
Substituting into the formula, we find the frequency of the wave:
[tex]f=\frac{5.2 m/s}{0.40 m}=13 Hz[/tex]
