NEET Physics Interference MCQ Question

Type: MCQ-numerical-Hard-Class 12

In an interference experiment with two coherent sources S1 and S2, the path difference at a point P is 7λ2\frac{7\lambda}{2}. What type of interference occurs at P?

A

Constructive interference with intensity 4I0

B

Constructive interference with intensity 2I0

C

Destructive interference with intensity 0

D

Destructive interference with intensity 4I0

Correct Answer

Option C

Detailed Explanation

According to the NCERT, destructive interference occurs when the path difference is (n+12)λ(n + \frac{1}{2})\lambda, resulting in zero intensity.
