Properties of Plane Mirror Images

Steps:

• Plane mirrors reflect light rays such that the image appears behind the mirror.
• The image is virtual because light rays diverge and do not converge in front of the mirror.
• The image is upright as the rays reflect without crossing over.
• The image size equals the object size due to the law of reflection maintaining equal angles.

Why D is correct:

• By the law of reflection, plane mirrors form virtual, upright images identical in size to the object, located at the same distance behind the mirror.

Why the others are wrong:

• A: Real and inverted images form with converging lenses or concave mirrors, not plane mirrors.
• B: Smaller images occur with convex mirrors, not plane mirrors.
• C: Plane mirror images are virtual, not real.

Final answer: D
