1. Images in a Curved Mirror
Convex Mirrors

2. Terminology of Convex Mirrors
The parts of a convex mirror and the imaging rules for a convex mirror are similar to those for a concave mirror
The difference is that F (now called a virtual focus) and C are behind the mirror and light rays seem to come from an apparent light source behind the mirror

3. How to locate the image in a convex mirror
Similar to a concave mirror, three light rays must be drawn originating from the top of the object:
Ray travels parallel to the PA and reflects in line with F (extend the ray straight behind the mirror with a broken line)
Ray aimed at F is reflected parallel to the principal axis (draw the incident ray behind the mirror with a broken line)
Ray aimed at C and reflects back along the same path (extend behind the mirror with a broken line)

4. Characteristics of the Image in a Convex Mirror
S – smaller
A – upright
L – located behind the mirror
T – virtual

5. Uses of Convex Mirrors
Security mirrors in stores – show a wide range of view with a smaller virtual image
Side-view mirrors on vehicles – “Objects in mirror are closer than they appear”
On front of school bus – allows drivers to see children both beside and in front of the bus
