Answer:
After, many research works were carried out the professionals and more over scientist came to know that the difference in the depth of the water reservoir or ocean can greatly effect the speed,s of the water molecules. While, at harbors there are some barriers or artificial boundaries for the ocean waves to experience. And due to the face off between the boundaries and the ocean waves there is a reflection phenomenon which occurs in the environment. Along, with that the depth around the harbor area is far less then the oceans normal deepness, and with that we know that there will be a decrease inside the speed,s of the ocean waves.
Step-by-step explanation:
Ocean waves:
The waves that are generated inside the water, due to the frictional agents or forces,F of the wind energy coming in contact with the surface molecules of the water. As the water molecules are subjected to the displacement,d from one point to another due to the force,F acting on them.
