Mirrors 3 – CONVEX Mirrors

Convex Mirrors A mirror with a surface curved outward is a convex mirror, also called a diverging mirror A convex mirror spreads out the rays.

Uses for Convex Mirrors Because convex mirrors allow you to see more than plane mirrors, they are often used for security in stores as well as rear-view mirrors in cars.

Images Formed by Convex Mirrors All images in a convex mirror are virtual. The reflected light rays never meet and the image appears to come from behind the mirror.

S- Smaller A-Upright L- Behind the mirror in front of F T- Virtual

Drawing a Convex Mirror Ray Diagram Steps Draw a line from the top of the object parallel to the principle axis to the mirror. Then draw a dotted line from there to the focal point. Draw a line from the top of the object to the focal point, and bound the reflective ray back parallel. Back track this parallel line through the mirror. It should be dotted. Ended here
