Straight Wave Pattern

A wave is a disturbance that moves energy from one place to another. Waves travel in different patterns depending on how they are created. Understanding wave patterns helps scientists predict how waves will move and where their energy will go.

Some waves travel in straight lines. A straight line is the shortest path between two points. When you watch ocean waves coming toward a beach, you can see them moving in long, straight rows. These waves form far out in the ocean when wind blows across the water surface. The wind creates waves that travel in the same direction, forming straight, parallel lines called wave fronts. Wave fronts are the leading edges of waves moving together.

Other waves travel in circular patterns. When you drop a pebble into a calm pond, you see ripples spreading outward in circles. The circles get bigger and bigger as the wave moves away from where the pebble landed. This happens because the energy spreads out equally in all directions from one point.

The shape of a wave pattern depends on its source. A large, moving source like wind blowing across the ocean creates straight wave patterns. A single point source, like a pebble hitting water, creates circular patterns. Both patterns carry energy, but they spread that energy differently across the water.
