NEET Physics Interference Assertion Reason Question
Assertion (A): At a point P on the perpendicular bisector of two coherent sources S1 and S2, the intensity of interference is 4I0.
Reason (R): The path difference S1P - S2P equals nλ for constructive interference.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
The NCERT context explains that when two coherent sources are in phase, the path difference being nλ results in constructive interference with intensity 4I0.
