Assertion (A): For a plane mirror, the angle of reflection is always equal to the angle of incidence. Reason (R): If an incident ray makes an angle of $35^\circ$ with the surface of a plane mirror, then the angle of reflection will also be $35^\circ$.

A is true but R is false. Explanation: Assertion (A) is true because the law of reflection states that the angle of incidence always equals the angle of reflection. However, Reason (R) is false because angles are measured from the perpendicular normal; an incident ray at $35^\circ$ to the mirror surface creates a $55^\circ$ angle of incidence ($90^\circ$ − $35^\circ$), making the angle of reflection $55^\circ$ as well.
