Physics-Interference

NEET Physics Interference Assertion Reason Question

Type: Assertion Reason-assertion-Easy-Class 12

Assertion (A): For two coherent sources, destructive interference occurs when the path difference is an odd multiple of half wavelengths. | Reason (R): Destructive interference results in zero intensity due to the phase difference of π.

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 but R is true.

Correct Answer

Option A

Detailed Explanation

Destructive interference occurs when the path difference is (n + 1/2)λ, leading to a phase difference of π, which cancels the waves resulting in zero intensity.
