NEET Physics Interference MCQ Question

Type: MCQ-diagram based-Hard-Class 12

In a setup with two coherent sources S1 and S2, if the path difference at a point P is such that S1P - S2P = (n + 1/2)λ (n = 0, 1, 2, 3,...), what will be the nature of interference at point P?

Question diagram
A

Constructive interference with maximum intensity

B

Destructive interference with zero intensity

C

Destructive interference with reduced intensity

D

Constructive interference with reduced intensity

Correct Answer

Option B

Detailed Explanation

According to the NCERT context, when the path difference is (n + 1/2)λ, destructive interference occurs, resulting in zero intensity.
