The image formed in a convex mirror is always virtual and erect, whatever be the position of the object. In this section, let us look at the types of images formed by a convex mirror.
- When an object is placed at infinity, a virtual image is formed at the focus. The size of the image is much smaller than compared to that of the object.

When an object is placed at a finite distance from the mirror, a virtual image is formed between the pole and the focus of the convex mirror. The size of the image is smaller than compared to that of the object.

Summary
S. No | Position Of Object | Position of Image | Size of Image | Nature of Image |
1 | At Infinity | At the focus F, behind the mirror | Highly diminished | Virtual and Erect |
2 | Between Infinity and the Pole | Between P and F, behind the mirror | Diminished | Virtual and Erect |
