Concave: Lens

Concave Lens, also known as a diverging lens, is a type of lens that is thinner at the center than at the edges. It is characterized by its inward-curved surfaces. Unlike a convex lens, which converges light rays, a concave lens causes parallel rays of light to diverge, or spread out. Concave vs. convex lenses Concave lenses—those that are thicker around the edges than they are in the center— disperse light rays, which can have the effect of making things look smaller or farther away. Convex lenses—those that dome outward and are thicker in the center than they are around the edges—make light rays converge. Concave describes shapes that curve inward, like an hourglass. Convex describes shapes that curve outward, like a football (or a rugby ball). If you stand… A convex mirror forms a diminished image, but a concave mirror, depending on the object's position, either forms an enlarged or diminished image. This is the
