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.
Concavevs.convexlenses Concavelenses—those that are thicker around the edges than they are in the center—disperselight rays, which can have the effect of making things look smaller or farther away.Convexlenses—those that dome outward and are thicker in the center than they are around the edg...
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—...

Which mirror is used by dentist? A concave mirrorgives the dentist a magnified reflection of the mouth while also refracting a bit of light. This means the image in the mirror is larger, brighter, and, for the dentist, easier to see. Another plus of using a concave mirror is that the...
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...
The concave mirror is the converging mirrors, due to the fact that when parallel incident rays fall on the surface of the mirror, the rays will reflect and meet at a particular point, i.e. focal point. Its shape is identical to a spoon. The reflecting surface of a concave mirror bent ...
