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


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.
