Question

In a plane mirror, why does the image distance equal the object distance?

Options

Choose one · Correct answer highlighted

Due to light converging behind the mirror Due to the mirror’s curvature Due to light dispersion Due to equal angles of incidence and reflection Correct

Explanation

In a plane mirror, light reflects such that the angle of incidence equals the angle of reflection. This symmetry ensures that the perpendicular distance from the object to the mirror equals the apparent distance of the image behind it, as the image forms along the normal extended backward.
