NEET Physics Interference MCQ Question
Consider a setup with two coherent point sources S1 and S2 producing interference on a screen. Which condition will result in destructive interference at a point P on the screen?
Path difference S1P - S2P = (n + 1/2)λ
Path difference S1P - S2P = nλ
Phase difference of 2π
Amplitude of sources being unequal
Correct Answer
Detailed Explanation
Destructive interference occurs when the path difference S1P - S2P equals (n + 1/2)λ, resulting in a phase difference that cancels the wave displacements.
