Discuss the position and nature of image formed by a convex mirror when an object is moved from infinity towards the pole of mirror.
Answer
In a convex mirror, the image formed is always virtual, upright and diminished. It is always situated between it's pole and focus irrespective of the distance of object in front of the mirror.
As the object comes closer to the mirror from infinity towards the pole, it's image shifts from focus towards the pole and increase in size.
The table below shows the position, size and nature of the image formed by a convex mirror
| No. | Position of the object | Position of the image | Size of the image | Nature of the image |
|---|---|---|---|---|
| 1. | At infinity | At focus | Diminished to a point | Virtual and upright |
| 2. | At any other point | Between focus and the pole | Diminished | Virtual and upright |
