3. Plane Mirror

4. Type of Image
Virtual
Equal in Size
Erect (Upright)

5. Spherical (Curved) Mirrors
Concave
Convex

6. Concave Mirror(Converging)

7. Concave Mirror

8. Converging Mirror

9. Summary for Concave Mirror
When object is:
Beyond C
At C
Between C and F
At F
Between F and mirror
Image is:
Between C and F
At C
Beyond C
No image
Virtual image

10. Mirror Equation
1 = 1 + 1
f do di

11. Magnification
M= hi = -di
ho do

12. Sign Convention do + object is in front of the mirror
di   +   real image, in front of the mirror
di    -   virtual image, behind the mirror
hi + erect image
hi - inverted image
f     +   converging (concave) mirrors
f     -    diverging (convex) mirrors

13. Convex Mirror (Diverging)

14. Convex Mirror (Diverging)

16. Summary for Convex Mirror
Always:
Virtual, reduced, upright image

17. Simulation
