Lens Optics (151-152)
BlackBoard Notes

======================= Photo - Click for a Larger Version =============================

======================= First Board Section =============================

• (Miller's drawing notes for ray diagrams on board: Draw axes first, then rays through the f's, then ray through lens center. Finally, draw lens)
• Converging lens, looking at a distant object:
  • Label the "Real Rays"

======================= Second Board Section =============================

• Diverging lens, distant object:
  • Label the "Virtual Rays"

======================= Third Board Section =============================

• Converging lens, close object:

• Converging lens, object closer than focal point:
  • Make sure image is labeled "Virtual"

======================= Fourth Board Section =============================

• Thin lens equation:

• f ≡ focal length: (+) converging lens, (-) diverging lens
• p ≡ object distance
• q ≡ image distance: (+) Real image, (-) Virtual image

======================= Fifth Board Section - If Needed! =============================

Lab Practical - next week!

• The lab will be locked during the day. Practice materials available in hallway study areas during lab hours.
