NEET Physics Interference MCQ Question
Refer to the diagram showing two coherent sources S1 and S2, and a point P on the perpendicular bisector. If the path difference between S1P and S2P is 2.5λ, what type of interference occurs at point P?
Constructive interference with maximum intensity.
Destructive interference with zero intensity.
Partial interference with reduced intensity.
No interference with unchanged intensity.
Correct Answer
Detailed Explanation
A path difference of 2.5λ corresponds to a phase difference of 5π, leading to destructive interference and zero intensity as per the NCERT context.
