Constructive Interference is a wave phenomenon that occurs when two waves (traveling in opposite directions) that have the same direction of displacement (either both positive or both negative) pass each other. The resulting wave is the sum of the displacements at the passing points.
So if one wave has a positive displacement of 2m and another wave (traveling in the opposite direction) has a displacement of 3m , when they pass by, the resulting wave which is "constructed" has a displacement of 5m (2m+3m=5m).
It is important to remember that the original two waves are not effected at all and continue traveling.
