Question

In the following image of the superposition of two water waves, the dark regions represent __________ interference.

  1. Constructive
  2. Destructive
  3. Both constructive and destructive
  4. Cannot say

hintHint:

Two interfering waves have opposite displacements.

The correct answer is: Destructive


    Destructive interference is just a type of interference which occurs anywhere along the medium where two interfering waves have opposite displacements. 
    In the following image of the superposition of two water waves, the dark regions represent Destructive interference.
