From this we can infer that:
| Object Position | Image Position | Nature | Size |
|---|---|---|---|
| Infinity | Focus | RI | Point sized |
| Beyond 2F | B/w 2F and F | RI | Diminished |
| 2F | 2F | RI | Same Size |
| b/w 2F and F | Beyond 2F | RI | Enlarged |
| Focus | Infinity | RI | Highly Enlarged |
| b/w P and F | Behind the object | VE | Enlarged |
