NEET Physics Interference MCQ Question
Consider two coherent sources S1 and S2 producing wave displacements at a point P. If the path difference S1P - S2P is equal to 1.5λ, what type of interference occurs at point P?
Constructive interference with maximum intensity.
Destructive interference with zero intensity.
Constructive interference with twice the intensity.
Destructive interference with minimum non-zero intensity.
Correct Answer
Detailed Explanation
A path difference of (n + 1/2)λ results in destructive interference, leading to zero intensity at point P, as given by the relationship S1P - S2P = (n + 1/2)λ.
