NEET Physics Interference Assertion Reason Question
Assertion (A): For two coherent sources, when the path difference is , the resultant intensity at a point is zero. | Reason (R): The displacement waves from the sources are out of phase, leading to destructive 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 but R is true.
Correct Answer
Detailed Explanation
When the path difference is , the waves are out of phase, leading to destructive interference and zero intensity as explained in the NCERT context.
