STANDARD Physics Interference MCQ Question

Type: MCQ-conceptual-Medium-Class 12

In the case of light waves from two coherent sources S₁ and S₂, there will be constructive interference at an arbitrary point P, if the path difference S₁P-S₂P is

A

(n + 1/2)λ

B

C

(n - 1/2)λ

D

λ/2

Correct Answer

Option B

Detailed Explanation
