## Unit 10: The Particle Model of Light

Learning ObjectivesBy the time you finish all labs, worksheets and related activities, you should be able to: 1. Use ray diagrams to account for the behavior of light when it encounters barriers and pinholes. 2. Determine how the separation between a point source and a detector affects light intensity. 3. State the Law of Reflection; use it to draw a ray diagram to locate the virtual image of an object formed by a plane mirror. 4. Use the Particle Model and ray diagrams to explain the shift in the path of a light ray as it passes from one medium to another. 5. Use Snell’s Law to determine angle of incidence, angle of refraction or critical angle. If curved mirrors and lenses are studied:6. Distinguish between the following terms: concave, convex, converging, and diverging. 7. State the relationship between radius of curvature and focal length. 8. Draw ray diagrams for concave and convex mirrors. Show the formation of both real and virtual images. Contrast features of virtual and real images. 9. Experimentally determine the relationship between object distance, image distance, and focal length for converging mirrors and lenses. 10. Given the thin lens equation, solve for object distance, image distance, or focal length for mirrors and lenses.

Chapter Notes B- supplements above presentation Chapter 29 Reflection Review- includes answers on a 2nd slide. Don't peak! Covers most, but not all you can expect on the test. Also think about how you answer the questions, not simply the answer. ## Refraction and Lenses
Day One- Snell's Law Lab
Diagrams and Formulas- Notes after the lab Refraction Topics- discusses Total Internal Refraction, Dispersion, ect Notes combined- good review power point with a different method of going over the topics. Includes a LOT of diagrams for help ## Review Videos- Reflection
BrightstormMirrors and Image formation- excellent examples of ray drawing on plane, convex, and concave mirrors. This is exactly what you need to be able to do by the end of the unit. Ray Diagrams: Geometric optics: great tutorial on how to exactly do this and do it accurately ## Review Videos- Refraction
Brightstorm
Reflection-Refraction - here it is again. Know this! Snell's Law- great explanation with examples on this Law Lenses- drawing lens diagrams Lens Equation |
