1. Between Focus $(F)$ and Center of Curvature $(C)$.
2. At Focus $(F)$.
3. Between Pole $(P)$ and Focus $(F)$.
| Images formed by a Concave Mirror |
| Position of the Object $(u)$ | Position of the Image $(v)$ | Size of the Image | Nature of the Image |
1. At Infinity | At Focus $(F)$ | Highly Diminished | Real and Inverted |
2. Beyond Centre of Curvature $(C)$ | Between Focus $(F)$ and Center of Curvature $(C)$ | Diminished | Real and Inverted |
3. At the Center of Curvature $(C)$ | At the Center of Curvature $(C)$ | Same Size | Real and Inverted |
4. Between Focus $(F)$ and Center of Curvature $(C)$ | Beyond Centre of Curvature $(C)$ | Enlarged | Real and Inverted |
5. At Focus $(F)$ | At Infinity | Highly Enlarged | Real and Inverted |
6. Between Pole $(P)$ and Focus $(F)$ | Behind the mirror | Enlarged | Virtual and Erect |
