NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): The angle of incidence is equal to the angle of reflection when a plane wavefront is reflected by a surface. | Reason (R): The congruence of triangles formed by incident and reflected wavefronts results in the equality of these angles.
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 the congruence of triangles EAC and BAC in the reflection of wavefronts leads to the equality of angles of incidence and reflection, supporting the assertion and reason.
