1. Mirrors

2. The Law of Reflection
The angle of incidence EQUALS the angle of reflection

3. Two types of curved mirrors:
Concave and Convex

4. Parts of a spherical mirror
C: Center of curvature
V: Vertex of mirror (center of mirror itself)
F: Focal point (parallel rays reflected from mirror converge at this point)
P: Principal axis (goes through C and F)
r: Radius of curvature (distance from C to V) (r = 2f)
f: Focal length (distance from F to V)

5. Rules of Mirror Ray Diagrams
Incident Rays
Are reflected 1
 Parallel to P
Through F 2
Parallel to P 3
Through C
Back on itself

6. Example 1 Image is located between _______ and ______
It is real/virtual
It is upright/inverted
It is reduced/enlarged/same size

7. Example 2 Image is located between _______ and ______
It is real/virtual
It is upright/inverted
It is reduced/enlarged/same size

9. Lenses

10. Two types of lenses:
Concave and Convex

11. Parts of a Lens O: Optical center F: Focal point
F’: Virtual focal point
P: Principal axis (goes through C and F)

12. Rules of Convex Lens Ray Diagrams
In to lens from object
Out from lens 1
 Parallel to P
Through F 2
Through O
Keep going straight

13. Example 1 Image is located between _______ and ______
It is real/virtual
It is upright/inverted
It is reduced/enlarged/same size

14. Rules of Concave Lens Ray Diagrams
In to lens from object
Out from lens 1
 Parallel to P
Through F’ 2
Through O
Keep going straight

15. Example 1 Image is located between _______ and ______
It is real/virtual
It is upright/inverted
It is reduced/enlarged/same size
