| S. No. | Position of object | Ray diagram | Position of Image | Nature of image | Size of image |
| 1. | At infinity |
| At focus $F$ | Real and inverted | Diminished |
| 2. | Between infinity and centre of curvature $C$ |
| Between centre of curvature $C$ and focus $F$ | Real and inverted | Diminished |
| 3. | At the centre of curvature $C$ |
| At the centre of curvature $C$ | Real and inverted | Same size |
| 4. | Between the centre of curvature $C$ and focus $F$ |
| Between infinity and the centre of curvature $C$ | Real and inverted | Magnified |
| 5. | At the focus $F$ |
| At infinity | Real and inverted | Magnified |
| 6. | Between focus $F$ and pole $P$ |
| Behind the mirror | Virtual and erect | Magnified |
