1 Mirrors Physics Mrs. Coyle

2 Plane Mirror d i =d o

3 Plane Mirror

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

5 Spherical (Curved) Mirrors Concave Convex

6 Concave Mirror(Converging) lens/lens.htm

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 = f d o d i

11 Magnification M= h i = -d i h o d o

12 Sign Convention d o + object is in front of the mirror d i + real image, in front of the mirror d i - virtual image, behind the mirror h i + erect image h i - inverted image f + converging (concave) mirrors f - diverging (convex) mirrors

13 Convex Mirror (Diverging)

14 Convex Mirror (Diverging)

15

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

18 Problem Find the image distance, height and type for a 5cm object placed 60cm from a concave mirror of focal length of 18cm. Answer: d i =25.7cm, h i =-2.14cm, Real, Inverted, Reduced
