Ch 18: Chapter 18: The Electromagnetic Spectrum and Light

About This Chapter

The Electromagnetic Spectrum and Light chapter of this Prentice Hall Physical Science Companion Course helps students learn the essential physical science lessons of the electromagnetic spectrum and light. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Electromagnetic Spectrum and Light textbook chapter.

How It Works:

  • Identify the lessons in Prentice Hall Physical Science's Electromagnetic Spectrum and Light chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the electromagnetic spectrum and light topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Color perception and the electromagnetic spectrum
  • Transparent and opaque materials
  • Wave refraction and Snell's Law
  • Properties of electromagnetic waves
  • Wave-particle duality
  • Regions of the electromagnetic spectrum
  • Light absorption, reflection and color

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.

Transparent and Opaque Materials in Electromagnetic Waves

2. Transparent and Opaque Materials in Electromagnetic Waves

What makes an object transparent or opaque? How does light pass through some objects and not others? And what about the other types of electromagnetic waves? We'll investigate all these questions in this lesson about the transparency and opacity of materials.

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

3. 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.

Electromagnetic Waves: Definition, Sources & Properties

4. Electromagnetic Waves: Definition, Sources & Properties

In this lesson, learn the basics of electromagnetic waves and how they make up the electromagnetic spectrum. We will explore the major trends and categories within the spectrum, as well as the various sources of electromagnetic waves.

Wave-Particle Duality: Concept, Explanation & Examples

5. Wave-Particle Duality: Concept, Explanation & Examples

Is light a particle with mass and substance? Or, is it just a wave traveling through space? Most scientists say light is both a particle and a wave! Find out how they came to this strange conclusion as we learn about the theory of wave-particle duality.

The 7 Major Regions of the Electromagnetic Spectrum

6. The 7 Major Regions of the Electromagnetic Spectrum

This lesson will walk you through each of the major regions of the electromagnetic spectrum. Explore the unique characteristics of X-rays, microwaves, radio waves, UV rays, infrared, gamma rays, and of course, visible light.

Color: White Light, Reflection & Absorption

7. 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.
