Answer 2

Explanation:

A convex lens is known as a converging lens. Rays from far-away object converge at the focus of the lens on the other side. As the object is brought closer to it but before the focus, the image formed is real, inverted and magnified. When the object is placed at focus, no image is formed. When the object is kept between focus and the pole, the image is virtual, erect and magnified and formed at the same side as the object.
