Interference

Constructive interference is when the crest of a wave is super positioned with the crest of another wave (or trough with trough). Destructive interference is when the crest of a wave is super positioned with the trough of another wave. An example of both would be sound waves. We can tell that it's constructive interference when the sound is louder and when it's destructive the sound gets quieter.
