On the surface we see water moving in the form of waves. Below the surface the water moves in great currents. Ocean Waves One of the things many people love about the ocean is the waves. People love to play in the waves, surf the waves, and the sound of the waves crashing on the beach.

A pebble striking the surface, Science waves of a boat, movement of the earth during an earthquake, or the wind. Here we focus on wind generated waves, although the same principles apply to all water waves.
Fetch is the distance over which the wind interacts with the water surface to creates waves. The longer the fetch the bigger higher the waves are. If the shore green in the diagram is a hill, there will be a wind shadow which gives protection from the wind, but even if the shore is flat as a pancake and gives no protection, the waves become progressively smaller as you for upwind to the shore.
Thus, rowing upwind toward shore is always an escape from waves. Height and Length of a simple wave also called a sine wave are indicated on the left. Motion of the water is different than the motion of the wave.
Thus, the velocity speed of a wave is not at all the same as the velocity of the water.
The horizontal movement of the water when a wave passes is approximately equal to the up and down movement of the water. If you are on flat water and are parallel to waves made by a passing boat, your boat will move side-to-side as much as up-and—down as the wave passes under you.
The side-to-side movement actually creates most of the difficulty in balancing the boat in such a situation. Using this knowledge in a common situation You are rowing along the shore of Angel Island and the fast ferry passes, creating a wave which becomes steep as it moves into shallow water near the shore.
As you realize this you try to pull your down-hill oar up out of the water, but this just pulls you over more in the bad direction. I spare you, gentle reader, a picture of the result.
The next time this happens try being more aggressive in leaning into the wave, but more importantly, you get your down-hill oar out of the water early. You can push the up-hill oar into the water to stablize the boat and prevent rolling too far in that direction.Longitudinal waves are waves where the disturbance moves in the same direction as the wave.
One example of this is a wave moving through a stretched out slinky or spring. One example of this is a wave moving through a stretched out slinky or spring. Links to all of the major sections for Revision Topics for Waves.
Feb 12, · About a hundred years ago, Einstein predicted the existence of gravitational waves, but until now, they were undetectable.

Winds at sea generate waves that average ten feet high; during storms, footers are common. But what creates waves the size of office buildings. Waves are responsible for basically every form of communication we use. Whether you're talking out loud, texting on your phone, or waving to someone in a crowd there's going to be a wave transmitting information.
