Short Answer

Is it possible to create a situation in which there is only destructive interference? Explain.

No, it is possible to have only destructive interference

See the step by step solution

Step by Step Solution

Step 1: Interference Pattern

The constructive and destructive interference patterns can be differentiated by the observed periodic maximum and minimum amplitude in an interference pattern.

Step 2: Explanation

Two coherent waves give an interference pattern after the superimposition of waves after the slits. However, if you introduce a dielectric piece with a thickness such that the path difference for the one coherent wave isλ/2 and then both coherent light waves will be completely out of phase Then we will see only the destructive interference pattern.
