Optics Review Topics
The following is a guideline for you to use while you study to ensure that you have covered most topics for the Optics unit test. The test covers Ch. 11-13. You have two mini-tests (Ch.11 and 12) to work with and a practice mini-test on the SSD for chapter 13. Good luck with your studies.
1. What is Light?
- Properties of light
- Electromagnetic spectrum
- Luminous source vs. non-luminous source
2. Different Ways of Producing Light
- I ncandescence, Phosphorescence, Electric Discharge, Fluorescence, Chemiluminescence, Bioluminescence, Triboluminescence, Light-Emitting Diode
3. The Ray Model of Light
- Terminology
4. Reflection of Light from a Plane (Flat) Mirror
5. The Laws of Reflection
- Two laws of reflection
- Specular reflection vs. Diffuse reflection
6. Images in Plane Mirrors
- Steps to locating images in plane mirrors
- Lateral Inversion
- SALT
7. Ray Diagrams for Images in Curved Mirrors
- Convex vs. Concave diagrams (know your rules!)
- Know the properties of concave/convex mirrors (chart in note)
8. Refraction
- Be able to explain why refraction occurs and how it differs going from a slower medium to a fast one and vice versa
- Be able to explain refraction phenomena like: rainbows, mirages, apparent depth, etc.
9. Index of Refraction
- n=c/v (know how to rearrange to solve for v)
- Know speed of light in air (vacuum) = 3.00x108 m/s
- Include all steps in problems (formula, units, summary statements, etc…)
- Enriched class: be able to use Snell’s Law (n=sinR/sinI)
10. Total Internal Reflection
- Critical Angle (know for water and diamonds)
- Know rules for total internal reflection
- Know everyday applications (fibre optic cables, triangular prisms, binoculars, periscopes, etc…)
11. Types of lenses
- divergent vs. convergent lenses and how you can differentiate them
12. Lens equation
- Be able to use the lens equation and the magnification equation to find di, do, hi, ho, M and f for different lenses.
13. Ray diagrams with lenses
- Be able to draw ray diagrams to show where the image of an object will appear. Be able to describe SALT of the image formed.
14. Human Eye
- be able to identify the parts of the eye
- be able to explain accommodation and how the conditions of myopia, presbyopia, and hyperopia occur and how they can be corrected
15. Applications of lenses
- Understand how a microscope, telescope, magnifying glass, projector, camera use lenses to form images.
