The rotating mirror, or concave mirror, has a bright spot set inward (away from the incident light). Concave mirrors reflect light inside one place. They are used to focus on light.
Centre of mirror curvature (C): It is the centre of the sphere that themirroris considered as a part of it. It lies in front of the reflecting surface in theconcave mirror, It lies behind the reflecting surface in theconvex mirror,Spherical mirrorshave only one centre of c...
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 in front of a concave mirror, your reflection will look taller. If you stand in front of a convex mirror, the opposite will happen—...

Meniscus lenses are convex–concave, i.e., convex on one side and concave on the other side. The contributions of both sides to the dioptric power cancel each other partially; overall the lens can be positive (focusing) or negative (defocusing). Positive meniscus lenses may be used for beam...

inward, resembling the shape of the inner surface of a hollow sphere. Concave mirrors are also converging mirrors because they cause light rays to converge or come together afterreflection. Depending on the position of the object and the mirror, concave mirrors can form both real and virtual ...
