  1. Lenses PhysicsMrs. Coyle

  2. What phenomenon is evident in lenses? https://wiki.brown.edu/confluence/display/PhysicsLabs/PHYS+0080+BC

  3. Basic Types of Lenses • Convex • Concave

  4. Convex Lens http://www.shokabo.co.jp/sp_e/optical/labo/lens/lens.htm

  5. Concave Lens http://www.shokabo.co.jp/sp_e/optical/labo/lens/lens.htm

  6. Type of Image • Real or Virtual • Enlarged or Reduced • Erect or Inverted

  7. Convex Lens f C Center

  8. Ray Diagram for Convex Lens Principal Axis http://facstaff.gpc.edu/~pgore/PhysicalScience/ray_diagram_sample.jpg

  9. Rules for Ray Diagrams for Convex Lens • A parallel ray refracts through the focal point. • A ray through the center of the lens continues straight. • A ray coming through the focal point, refracts parallel to the principal axis.

  11. When the object is: Beyond 2F At 2F Between 2F and F At F Between F and lens Then the image is: Between 2F and F At 2F Beyond 2F No image Virtual image Summary for Convex Lens

  12. Sign Convention do  +    object distance di   +   real image, other side of lens di    -   virtual image, same side as object hi + erect image hi - inverted image f     +   converging lens (convex) f     -    diverging lens (concave)

  13. Magnification M = hi = -di ho do Note: When magnification is <0, the image is inverted.

  14. Lens Equation 1 = 1 + 1 f do di

  15. Concave Lens Object Image

  16. Summary for Concave Lens Always: • Virtual, reduced, upright image
