This comprehensive guide from Bright Tutorials covers everything you need to know — with clear explanations, exam tips, and key points for board exam preparation.

Concave Mirror Properties
- Converging mirror — reflects light inward towards a focus point
- Can form real (inverted) and virtual (erect) images depending on object position
- Image changes from virtual enlarged → real inverted as object moves from F to beyond C
- Uses: shaving mirror, torch reflector, dentist's mirror, solar concentrator
Convex Mirror Properties
- Diverging mirror — reflects light outward
- Always forms virtual, erect, diminished image regardless of object position
- Image forms between P and F, behind the mirror
- Uses: rear-view mirror in vehicles (wider field of view), security mirrors
Key Differences
- Focal length: Concave = negative, Convex = positive
- Image type: Concave = real or virtual, Convex = always virtual
- Image size: Concave = can be enlarged, Convex = always diminished
- Field of view: Concave = narrow, Convex = wide
- Reflecting surface: Concave = inner, Convex = outer
