Describe with the help of a ray diagram the nature, size and position of the image formed when an object is placed at infinity (considerable distance) in front of a convex lens. State three characteristics of the image so formed.

Ray diagram showing the nature, size, and position of the image formed when an object is placed at infinity (considerable distance) in front of a convex lens.

The three characteristics of the image so formed are:

Explanation

When an object is at a considerable distance (or infinity) in front of a convex lens, then the image formed is real, inverted, much smaller than the object (or highly diminished), and at the focus $(F)$ on the other side of the lens.
