How do wave trains travel? How do they interact with each other?
· Wave trains are the progression of dispersed swells. One wave train contains waves that are all the same relative wavelength. The train moves half as fast as individuals in the train.
· Various sizes of wave trains exist in an area at the same time. Longer waves moves faster than shorter waves. These wave trains can be coming in from different storms.
· When wave trains interact with each other, it is called interference. There are two types of interference: destructive and constructive.
· Destructive interference occurs when two wave trains subtract from each other. There is a cancellation effect on the wave energy. This produces almost no waves at all.
· Constructive interference happens when wave trains add to each other. These are bigger than the size of each wave train.
