Curved Mirrors | Concave and Convex Mirrors

Curved Mirrors

A curved mirror is a reflecting surface with a curvature, typically shaped as part of a sphere (spherical mirror), that either bulges inward (concave) or outward (convex). These mirrors manipulate light rays to form magnified, diminished, or distorted images, depending on the curvature type and object distance.

1. Why concave mirror can form real and virtual images?

Depends on object position relative to focus.

2. Why convex mirror is safer for vehicles?

Provides wider field of view.

3. Why sign convention is needed?

To solve numerical problems correctly.

4. Why image at infinity when object at focus?

Reflected rays become parallel.

5. Why convex mirror always forms diminished image?

Due to diverging nature of rays.
