Physics - Optics - Reflection - Curved mirrors (concave and convex) - Concave and Convex Mirrors

A 5-step lesson. Step 1: 'Key terms: Center of curvature (C) = center of the sphere the mirror is part of. Focal point (F) = midpoint between C and mirror. Focal length (f) = distance from mirror to F = R/2. Principal axis = line through C and F.' Step 2: 'Concave mirror (converging): Reflecting sur
