  1. REY DIAGRAMS for THIN LENSES This is an example how teacher make presentation for students learning “REY DIAGRAMS” : • Evaluation previous students knowledge: • Various lens shapes. Converging and diverging lens. (Slide 2) • Focal point. Students nows answer. (Slides 3,4) • Small problem: We have thin lens and an object. Where is the image located? Teacher to lead, adding qestions for students, discuss. (Slide and animation 6) 3. Experiment: Small problem, students answer, coputers answer. (Slide 7) 4. A few groups take a (simple) question. (Slides 8,9) 5. An answer. (Slide 10)

  2. Various thin lens shapes(nlens>nmedium): Biconvex, plano-convex, concave-convex 1. Converging lenses, 2. Focal length>0, 3. Thickest at the middle Biconcave, plano-concave, convex-concave 1. Diverging lenses, 2. Focal length < 0, 3. Thickest at the edges

  3. HOW DOES RAYS DIRECTION AFTER REFRACTING ? Focal point FOCAL POINTCONVERGINGLENS
