Question

In the following image of the superposition of two water waves, the bright regions represent _______ interference,

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

hintHint:

Two in phase waves having the same frequency meets at the same place at the same time

The correct answer is: Constructive


    Constructive wave interference is a wave interference which occurs when in phase waves meets with each other and forms a new wave with greater amplitude. When two in phase waves having the same frequency meets at the same place at the same time, the amplitudes of the two waves are simply added together.
    In the following image of the superposition of two water waves, the bright regions represent Constructive interference.
