Surfing The Big Kahuna

 

 This Surfboard is a great fusion between the wave

 catching ability of a longboard and the snappy   

 responsiveness of a shortboard. It's a little bit of

 the best of both worlds.

 Formation of Waves

  1. Wind blows over the sea surface.
  2. The surface of the sea exerts frictional drag on the lower layer of the wind.
  3. The top layer (with the least drag) moves faster than the lower layer and hence tumbles over it.
  4. This causes a circular motion of wind energy that acts on the sea to create waves.

What Causes Waves?

The winds cause waves on the surface of the ocean (and on lakes). The wind transfers some of its energy to the water, through friction between the air molecules and the water molecules. Stronger winds (like storm surges) cause larger waves. You can make your own miniature waves by blowing across the surface of a pan of water.

 

Waves of water do not move horizontally, they only move up and down (a wave does not represent a flow of water). You can see a demonstration of this by watching a floating buoy bob up and down with a wave; it does not, however, move horizontally with the wave. See the animation below.

 

Tsunamis (incorrectly called tidal waves) are different from surface waves; they are caused by underwater earthquakes, volcanic eruptions, or landslides.

 

Waves can be represented by simple harmonic motion.
