Image Formation by Concave and Convex Mirrors
| Mirror Type | Object Position | Image Position | Image Size | Image Nature | Image Side |
|---|---|---|---|---|---|
| Concave | At infinity | At \( F \) | Highly diminished (point-sized) | Real, Inverted | Other side (In front of the mirror) |
| Concave | Beyond \( C \) | Between \( F \) and \( C \) | Diminished | Real, Inverted | Other side |
| Concave | At \( C \) | At \( C \) | Same size | Real, Inverted | Other side |
| Concave | Between \( F \) and \( C \) | Beyond \( C \) | Magnified | Real, Inverted | Other side |
| Concave | At \( F \) | At infinity | Highly magnified | Real, Inverted | Other side |
| Concave | Between \( F \) and Pole | Behind the mirror | Magnified | Virtual, Erect | Same side (Behind the mirror) |
| Convex | Anywhere in front of the mirror | Behind the mirror (between \( P \) and \( F \)) | Diminished | Virtual, Erect | Same side (Behind the mirror) |
Image Formation by Convex and Concave Lenses
| Lens Type | Object Position | Image Position | Image Size | Image Nature | Image Side |
|---|---|---|---|---|---|
| Convex | At infinity | At \( F \) | Highly diminished (point-sized) | Real, Inverted | Other side (Behind the lens) |
| Convex | Beyond \( 2F \) | Between \( F \) and \( 2F \) | Diminished | Real, Inverted | Other side |
| Convex | At \( 2F \) | At \( 2F \) | Same size | Real, Inverted | Other side |
| Convex | Between \( F \) and \( 2F \) | Beyond \( 2F \) | Magnified | Real, Inverted | Other side |
| Convex | At \( F \) | At infinity | Highly magnified | No image is formed | N/A |
| Convex | Between \( F \) and Optical Center | Behind the lens | Magnified | Virtual, Erect | Same side (In front of the lens) |
| Concave | Anywhere in front of the lens | Between \( F \) and Optical Center | Diminished | Virtual, Erect | Same side (In front of the lens) |
