Given:
Velocity of water waves = 1.8 m/s
Wavelength = 4.4 m
Let's find the frequency the water waves meet th doc.
To find the frequency, apply the formula:
![f=(v)/(\lambda)](https://img.qammunity.org/2023/formulas/physics/high-school/puugc9221m5n0c13uxcss75flkr0bngwjo.png)
Where:
v is thevelocity = 1.8 m/s
λ is the wavelength = 4.4 m
f is the frequency
Thus, we have:
![\begin{gathered} f=(1.8)/(4.4) \\ \\ f=0.409\text{ Hz} \end{gathered}](https://img.qammunity.org/2023/formulas/physics/college/6xhdspziunwrrr2v0yddkrrk6acbc49nn9.png)
Therefore, the frequency is 0.409 Hz
ANSWER:
0.409 Hz.
