NEET Physics Interference Assertion Reason Question
Assertion (A): In a two-source interference pattern, when the path difference between the waves is an odd multiple of half the wavelength, destructive interference occurs.
Reason (R): Destructive interference results in zero intensity due to the waves being out of phase at that point.
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 states that destructive interference occurs when the path difference is (n + 1/2)λ, resulting in zero intensity because the waves are out of phase.
