  3. Plane Mirror http://physics.bu.edu/~duffy/py106/Reflection.html

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

  5. Spherical (Curved) Mirrors • Concave • Convex

  6. Concave Mirror(Converging) http://www.shokabo.co.jp/sp_e/optical/labo/lens/lens.htm

  7. ConcaveMirror

  8. Converging Mirror http://buphy.bu.edu/~duffy/PY106/22a.GIF

  9. 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 Summary for Concave Mirror

  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) http://www.shokabo.co.jp/sp_e/optical/labo/lens/lens.htm

  14. Convex Mirror (Diverging)

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

  16. Simulation • http://higheredbcs.wiley.com/legacy/college/halliday/0471320005/simulations6e/index.htm?newwindow=true

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