Convex Mirrors Surface of mirror is curved outward Spreads out light rays (“diverging” mirror) Produces a virtual image that is upright and smaller than the object Surface of mirror is curved outward Spreads out light rays (“diverging” mirror) Produces a virtual image that is upright and smaller than the object

Ray Diagrams for Convex Mirrors Ray 1: travels parallel to the principal axis and reflects through the focal point

13
Ray Diagrams for Convex Mirrors Ray 2: travels towards the focal point and reflects parallel to the principal axis

14
Ray Diagrams for Convex Mirrors The image appears where the (virtual) reflected rays appear to intersect
