This document discusses convex mirrors and how images are formed using ray tracing. It explains that a convex mirror's reflecting surface bulges outward and that images formed in convex mirrors are always virtual, upright, and smaller than the object. The document uses ray tracing diagrams to show how parallel, focal, and straight rays reflect off a convex mirror and locate the virtual image. Applications of convex mirrors mentioned include makeup/shaving mirrors and wide-angle mirrors used on cars or at blind intersections.
