Lens Formation of Virtual and Enlarged Image

Introduction:
A lens is a transparent material with curved surfaces that refracts light to converge or diverge the rays. Depending on the shape of the lens, it can form different types of images - real or virtual, magnified or diminished. In this case, we are looking for a lens that forms a virtual and enlarged image.

Convex Lens:
A convex lens is thicker in the middle and thinner at the edges. When light rays pass through a convex lens, they converge and meet at a point called the focal point. This is the point where the lens forms an image. Depending on the position of the object, the image can be formed either on the same side of the lens as the object (real image) or on the opposite side (virtual image).

Virtual Image Formation:
A virtual image is formed when the light rays appear to diverge from a point behind the lens. In the case of a convex lens, a virtual image is formed when the object is placed closer to the lens than its focal length. The virtual image is always erect and appears larger than the object.

Enlarged Image Formation:
An enlarged image is formed when the size of the image is larger than the size of the object. In the case of a convex lens, an enlarged image is formed when the object is placed closer to the lens than its focal length. The convex lens converges the light rays, causing them to diverge and form an enlarged virtual image.

Explanation:
Based on the above information, the correct answer to the given question is option 'A' - Convex lens. A convex lens can form a virtual and enlarged image when the object is placed closer to the lens than its focal length. The convex lens converges the light rays, causing them to appear to diverge from a point behind the lens, forming a virtual image that is larger than the object.
