A linear object is placed on the axis of a lens. An image is formed by refraction in the lens. For all positions of the object on the axis of the lens, the positions of the image are always between the lens and the object.
(i) Name the lens.
(ii) Draw a ray diagram to show the formation of the image of an object placed in front of the lens at any position of your choice except infinity.

Explanation

**Step-by-Step Solution:**

**(i) Name the lens.**

The lens described in the question is a **concave lens**. This is because a concave lens always produces virtual images that are located between the lens and the object, regardless of the object's position along the axis.

**(ii) Draw a ray diagram to show the formation of the image of an object placed in front of the lens at any position of your choice except infinity.**
