NEET Physics Interference MCQ Question
Consider a setup with two coherent point sources S1 and S2 producing a pattern of interference fringes on a screen. If the path difference between light from S1 and S2 to a point on the screen is , what type of interference occurs at that point?
Destructive interference due to the path difference
Constructive interference due to the phase difference
Destructive interference due to the phase difference being zero
Constructive interference due to the path difference
Correct Answer
Detailed Explanation
According to the NCERT context, a path difference of results in destructive interference. Here, fits this condition with .
