Question

A reflected image is shown below. Identify the reflective surface. 

• A. Concave surface
• B. Convex surface
• C. Cylindrical surface
• D. Conical surface

Hint:

A convex surface always spreads and compresses reflections, making the center look narrow and edges stretched.

Answer 1

The Correct Option is B

Step 1: Observing the distortion.
The reflected text appears stretched horizontally toward the edges and compressed near the center, forming a characteristic outward bulge. This indicates that the reflecting surface curves *outward*.

Step 2: Explanation.
- Concave surfaces (A) curve inward and typically produce magnified or inverted reflections depending on distance — not the outward-stretched effect seen here.
- A convex surface (B) bulges outward and causes the reflected image to spread horizontally with reduced central width — exactly like the distorted text in the image.
- Cylindrical (C) and conical (D) surfaces distort only in one axis or unevenly, not in the smooth bulging manner seen here.

Step 3: Conclusion.
Thus, the reflective surface in the image is a convex surface.
