What exactly is a magnifying lens?
A magnifying lens is a convex lens that is thicker in the middle and thinner at the edges. It is used to enlarge the apparent size of objects when viewed through it by bending light rays inward, causing them to converge and produce a magnified image.

A magnifying lens is a convex lens (option C) that is thicker in the middle and thinner at the edges. This type of lens is designed to bend light rays inward, converging them to a focal point on the opposite side of the lens. When an object is placed within the focal length of the lens, a magnified virtual image is formed on the opposite side. This magnification effect allows for easier viewing of small objects or details that are otherwise difficult to see with the naked eye. Magnifying lenses are commonly used in various applications such as magnifying glasses, microscopes, and cameras to enhance visual clarity and detail. Unlike plane-concave lenses (option A), concave lenses (option B), or cylindrical lenses (option D), convex lenses are specifically shaped to create magnification by focusing light rays to produce enlarged images.
