Question

An object is placed at a far distance in front of a thin converging lens. Then the object (1 point) moves gradually toward the lens along the optical axis, stopping when it nearly touches the lens. As the object moves, what set of images does the lens form of it over time? A. real, and then virtual B. virtual, and then real C. real only virtual only

Answer 1

real, and then virtual

Step-by-step explanation:

A converging lens is known as convex lens. This lens is called converging lens because it converges all light rays incident on the lens and parallel to the principal axis at the focus.

The nature of image formed by objects placed in front of this lens as mostly REAL IMAGES. The image formed becomes virtual only when the object is almost in close contact with the lens.

Based on the explanation, it can be deduced that an object placed far from a convex lens forms real images but as we move closer to the lens (almost touching the lens), the image formed overtime tends to be virtual.
