### Module Question

What does it mean when the peak of one wave interacts with the trough of another wave?

This is called destructive interference. In a way the peak of one wave and the trough of one another cancel each other out. However the don't cancel each other out unless their amplitude or the height of the peak/trough are equal and the waves line up perfectly. Otherwise only partial parts of one peak or trough will decrease.

The opposite, when the peak of one wave corresponds with the peak of another or when the trough of one wave corresponds with another, is called constructive interference.
