What type of mirror always produces a virtual, upright, and diminished image of a real object regardless of object distance?
Answer and explanation
Correct answer: A. Convex mirror
- Step 1: A convex spherical mirror has a diverging reflective surface that causes reflected rays to diverge.
- Step 2: Extending these diverging rays behind the mirror forms an image that is always virtual, upright, and smaller in size (diminished).
Answer
Convex mirror.
Why not the others: 'Concave mirror' can form real, inverted, magnified or diminished images depending on position; 'Plane mirror' forms virtual upright images of identical size; 'Parabolic converging mirror' acts like a concave mirror.
