In a Convex Mirror Focus and Center of Curvature is behind the mirror so that objects can be placed at only two positions. Check all diagrams and data given below to find out how we can find image position, its nature, and its size using Ray Diagrams for a Convex Mirror.
Case - 1
Object(AB) is placed at infinity
Result:-
| Object Position | At Infinity |
|---|
| Image Position | At Focus (F), Behind Mirror |
|---|
| Nature of Image | Virtual and Erect |
|---|
| Image Size | Point Sized |
|---|
Case - 2
An object placed between Infinity and Pole (P)
Result:-
| Object Position | Between Infinity and Pole (P) |
|---|
| Image Position | Between Focus (F) and Pole (P), Behind Mirror |
|---|
| Nature of image | Virtual and Erect |
|---|
| Image Size | Smaller |
|---|
Let's Summarise it all
| Object Position | Image Position | Nature of Image | Image Size |
|---|
| Infinity | Focus (F), Behind Mirror | Virtual and Erect | Point Sized |
| Between Infinity and Pole (P) | Between Focus (F) and Pole (P), Behind Mirror | Virtual and Erect | Smaller |
Uses of Convex Mirror
- It's used as a rear mirror in vehicles. As they give the erect but diminished image and it also provides a wide range view as it is curved outwards.
