Convex mirrors are often used as sideview mirrors on cars. Many such mirrors display the warning "Objects in mirror are closer than they appear." Assume that a convex sideview mirror has a radius of curvature of 14.3 m and that a car is 12.1 m behind the mirror. For a flat mirror, the image distance would be 12.1 m, and the magnification would be 1. (a) Find the image distance for this convex mirror. m (b) Find the magnification for this convex mirror.
