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
nλ
C
(n - 1/2)λ
D
λ/2
Correct Answer
Option B
Detailed Explanation
Constructive interference occurs when the path difference between two waves is an integral multiple of the wavelength, i.e., nλ.
