Concave and convex mirrors differ in their shape and curvature, which has an impact on how they are designed and made. The difference between concave and convex mirror lies at the heart of their distinct behaviors and impacts on the reflection of light. A reflecting coating on the inner surface of a skillfully bent glass or metal substrate must frequently be precisely shaped for concave mirrors. Convex mirrors, on the other hand, can be created by coating the exterior of a substrate that is evenly curved.
