Ch 20: CEOE Physical Science: Light, Mirrors & Lenses

About This Chapter

Review the composition, behavior and nature of light by viewing the lessons in our Light, Mirrors & Lenses chapter. Add this refresher course to your preparation strategy as you approach the CEOE Physical Science exam.

CEOE Physical Science: Light, Mirrors & Lenses - Chapter Summary

Let these short videos refresh your knowledge of the science behind how light behaves, why we see color, and more. The lessons include the information given below:

  • Origin of light, color frequencies and spectrum
  • Composition of white light and occurrence of color
  • Definition of reflection, refraction and dispersion, Snell's Law
  • Types and sources of light rays
  • How to answer mirror questions with equations

This refresher course offers a multi-faceted approach that you can adapt to your own personal needs and learning style. If you prefer a visual format, our short yet informative and brightly-written videos are right for you. If you prefer reading to viewing, the fully-transcribed text version of the lesson may be more suitable. Quizzes and chapter tests reinforce the material, and the dashboard helps you stay on track.

CEOE Physical Science: Light, Mirrors & Lenses Chapter Objectives

The CEOE Physical Science test is part of a battery of competency-based and criterion-referenced examinations that comprise the teacher certification and endorsement process for the state of Oklahoma. This course and the lessons contained in it are aligned to the competencies under Subarea II: Motion, Forces and Energy. Subarea II makes up 32% of the exam.

The CEOE Physical Science exam is computer-based, with 80 multiple-choice questions and one for which you must compose a written response. The constructed-response assignment may refer to any of the three subareas that comprise the test. Your composition must meet the length requirement of 300 to 600 words.

The Nature of Light: Origin, Spectrum & Color Frequency

1. The Nature of Light: Origin, Spectrum & Color Frequency

This lesson introduces the basics of visible light and color. Learn how the visible light spectrum is divided into the six color ranges. We'll also discuss why different people name colors in different ways.

Reflection: Angle of Incidence and Curved Surfaces

2. Reflection: Angle of Incidence and Curved Surfaces

How do waves reflect off of surfaces? How do we account for the images that we see reflected in various objects? Discover the answers to these questions as we investigate the rays and angles defining the law of reflection.

Color: White Light, Reflection & Absorption

3. Color: White Light, Reflection & Absorption

What gives color to objects? How do light waves interact with materials to produce red and green or white and black? In this lesson, learn how white light is composed of all colors and how absorption and reflection influence our color perception.

Refraction & Dispersion: Definition, Snell's Law & Index of Refraction

4. Refraction & Dispersion: Definition, Snell's Law & Index of Refraction

Refraction explains why light bends in water. But, did you know that mathematical laws determine exactly how light waves are bent? In this lesson, we'll explore the mechanics of wave refraction, including Snell's Law and the index of refraction.

Light Rays: Definition, Types & Sources

5. Light Rays: Definition, Types & Sources

This lesson will explain what light rays are, the main types of light rays, and how they can be simulated using lasers or beams of light. A short quiz will follow.

Using Equations to Answer Mirror Questions

6. Using Equations to Answer Mirror Questions

After watching this lesson, you will be able to answer questions on mirrors, stating whether an image is real or virtual, upright or inverted, and larger or smaller. A short quiz will follow.
