2. Types of Curved Mirrors
To make a curved mirror, you make part of the surface of the sphere reflective. There are 2 types:
1) Concave (Converging) Mirror- shaped like part of the surface of a sphere in which the inner surface is reflective.
2) Convex (Diverging) Mirror- shaped like part of the surface of a sphere in which the outer surface is reflective.

3. Uses of Convex Mirrors Security Mirrors
Diverging mirrors are used because they contain more visual information then regular mirrors, hence they give a wider angle of view.
Security Mirrors
Stores use convex mirrors to provide a wide field of view for security.
Convex mirrors always produce virtual, upright, and smaller images.

4. Uses of Convex Mirrors Rear View Mirrors
Some cars, buses, and trucks use convex mirrors on one of the rear view mirrors.
Convex mirrors produce a wider field of view, thereby providing the driver more view in all directions.
Our brain interprets small objects as always being farther away than large objects. Because the convex mirror produces smaller images, we assume that the object must be far away. Therefore, some mirrors have a message saying that objects are closer than they appear.

5. Convex Mirror Terminology
Principal Axis- the line through the centre of curvature to the midpoint of the mirror.
Vertex- the point where the principal axis meets the mirror. Labelled V.

6. Focus- The point a which rays parallel to the principal axis extended backward behind the mirror converge. Labelled F.
Centre of Curvature-The centre of the sphere whose surface has been used to make the mirror. Labelled C.

7. Locating Images in Convex Mirrors
To determine the image of an object in front of a concave mirror you need to draw at least two incident rays from the top of the object.
RULES:
1) A light ray parallel to the principal axis reflects out as though coming from the focus
2) A light ray through the centre of curvature is reflected back onto itself.
3) A ray directed at the focus will reflect parallel to the principal axis.
4) A ray aimed at the vertex will follow the law of reflection.
