A convex mirror is a spherical mirror in which the reflection of light is on the concave surface i.e. the curved surface. The mirror whose reflective surface is facing outwards is called a convex mirror. Convex mirrors reflect light outward. Convex mirrors are used in the doors of a house, convex mirrors are used in vehicles to see vehicles coming from behind. A concave mirror-The mirror whose reflective surface remains inward is called a concave mirror. The concave mirror reflects the light cup inward, so the dentist uses it for shaving, torch, solarium, and headlight. Let's test your knowledge about the Convex and Concave Mirror Quiz.
