Discuss the position and nature of image formed by a convex mirror when an object is moved from infinity towards the pole of mirror.

Explanation

### Step-by-Step Solution

1. **Understanding Convex Mirrors**:
- A convex mirror is a spherical mirror that bulges outward. It always produces images that are virtual, erect, and diminished, regardless of the position of the object.

2. **Position of the Object**:
- When the object is at infinity (very far from the mirror), the rays of light coming from the object are parallel. When these parallel rays strike the convex mirror, they diverge after reflection.
