NEET Physics Interference Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 12

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.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false.

Correct Answer

Option A

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.
