2. Concave Mirrors
Object between the focal point and the center of curvature. C f

3. Concave Mirrors
Object at the center of curvature. C f

4. Concave Mirrors
Object further than the center of curvature. C f

5. Concave Mirrors
Object closer than the focal point. f C

6. Convex Mirrors
Object closer than the focal point. f

7. Convex Lens Object between the focal point and twice the focal point.

9. Diagram Summary
Draw an incident ray parallel to the center line. The reflected/refracted ray goes through the focal point.
Draw an incident ray from the mirror/lens to the focal point through the top of the object. The reflected/refracted ray is parallel to the center line.

10. Diagram Summary Where the rays meet shows the image.
The diagram shows if the image is real or virtual, upright or inverted, smaller or magnified (or the same).
If the reflected/refracted lines never meet, the image is a virtual image and can not be projected on paper.
