Expert-verifiedIs it possible to create a situation in which there is only destructive interference? Explain.
No, it is possible to have only destructive interference
The constructive and destructive interference patterns can be differentiated by the observed periodic maximum and minimum amplitude in an interference pattern.
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 is and then both coherent light waves will be completely out of phase Then we will see only the destructive interference pattern.
