Concave and Convex Mirrors: A concave mirror is one where the center of curvature lies on the R-side so the R > 0 and f > 0 and a convex mirror is one where the center of curvature lies on the V-side so that R < 0 and f < 0 . concave f > 0 convex f < 0 Flat Mirror: A flat mirror is the limiting case where the radius R (and thus the local length f ) become infinite.
