13.2 Images Formed by Mirrors
BeginnerMCQMathematicalConceptual13.9k
A horizontal principal axis line runs continuously across two side-by-side optical diagrams. On the left, a concave spherical mirror is depicted as a thin vertical arc curving inward toward the left, with its reflective surface facing left. A point labeled F is on the axis to the left of the mirror, and a point labeled C is further left along the axis. On the right, a convex spherical mirror is depicted as a thin vertical arc curving outward toward the left, with its reflective surface facing left. Points labeled F and C are on the axis to the right of the mirror, behind the reflective surface. Horizontal arrows labeled 'Incident light' point from left to right toward each mirror surface. No other labels, lines, text, or axes appear.
Schematic representation of a concave mirror and a convex mirror.
A concave spherical mirror has a focal length of magnitude \(15 \, \text{cm}\). A convex spherical mirror has a radius of curvature of magnitude \(30 \, \text{cm}\). According to standard optical sign conventions, what are the radius of curvature \(R_{\text{concave}}\) of the concave mirror and the focal length \(f_{\text{convex}}\) of the convex mirror?
