Physics-Interference
NEET Physics Interference Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): In Young's double-slit experiment, if the path difference between two light waves is (n + 1/2)λ, destructive interference occurs. | Reason (R): Destructive interference results in zero intensity when the phase difference is an odd multiple 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
According to the NCERT context, destructive interference occurs at a point where the path difference is (n + 1/2)λ, leading to a phase difference of an odd multiple of π, resulting in zero intensity.
