Interference

Construtive inteference is when two or more waves go together and they combine a whole wave, a deconstructive wave is when two waves meet and they and both crests line up together.

Deconstructive: when two cars get into a car crash... They both line up they do not end up on a v shape.. They crash in a vertical line. Which means two forces going together leading into one "line"

Constructive: when two ocean waves go together and they crash making another huge wave showing it is constupructive wave,
