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.
