Wave interference is the result of two or more waves meeting each other at a particular point in space at the same time.
What is Constructive Wave Interference?
In a constructive wave interference, the amplitudes are in the same direction. Therefore, when they meet each other, the resultant is larger than the waves involved in the addition.
What is Destructive Wave Interference?
In a destructive wave interference, the amplitudes of the waves are in the opposite direction: some are in the positive side and some in negative. Because there are positive ones and negative ones, the waves either cancel out or subtract. Consequently, the resultant is small than the waves used in the acquirement of the interference.
