interference
It's called Constructive. (:Just found the answer.
Constructive interference can be a confusing concept when called interference. It is wave interference that is moving in phase with another wave. This causes the waves to for a resultant wave with a greater amplitude. Destructive interference is wave interference that is moving out of phase with another wave. These waves form a resultant wave of lower amplitude.

When waves act together, you talk about "interference".When they reinforce each other, it is "constructive interference".When they cancel each other, it is "destructive interference".
constructive interference
constructive or destructive interference
When the crest of one wave overlaps the trough of another, this produces destructive interference. If both original waves are equal in amplitude, then nothing will remain. The waves completely cancel out. However, if one waver is larger in amplitude, then there will still be a wave left over after they meet, but it will be smaller. The amplitude of the new wave will be the larger wave amplitude minus the smaller wave amplitude one. The opposite can also occur. If the crests of two waves overlap, then it produces constructive interference (resulting in one larger wave).
