How do wave trains travel? How do they interact with each other? What will be an ideal response?

ANS:Answer
should include:
? 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.
