Presentation Transcript

  1. Mirror, mirror on the wall!

  2. Image Formation - Plane or Flat Mirror

  3. Magnification M = = -1 and p = q

  4. Concave, a Spherical Mirror

  5. Some Rules to Live By!

  6. DO NOT TRY THIS AT HOME Do not steal makeup or dentist’s mirror Do not crumple up a kid’s first grade homework Do not hold up mirror to sun, paper near mirror Do not burn paper

  7. Image Formation in Concave Mirrors

  8. Mirror Equation: For parallel incoming rays, q is at focal point f = R / 2

  9. Lenses

  10. Thick and thin • One, two sided (alike/different) • Converging and Diverging

  11. SIMILAR! • Concave Mirror & Biconvex Lens • Convex Mirror & Biconcave lens DIFFERENT! Two radii of curvature, +ve and –ve (back and front) Two focal points FRONT, BACK Sign convention: +ve image distance at back of lens (“natural”) location

  12. SIGN CONVENTIONS
