Ch 22: Holt Physical Science Chapter 22: The Nature of Light

About This Chapter

The Nature of Light chapter of this Holt Physical Science Textbook Companion Course helps students learn essential physical science lessons of light. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with The Nature of Light textbook chapter.

How it works:

  • Identify the lessons in Holt Physical Science The Nature of Light chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the nature of 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 about:

  • Sources and properties of electromagnetic waves
  • Light's origin, spectrum and color frequency
  • Seven major regions of the electromagnetic spectrum
  • Snell's Law in relation to refraction and dispersion
  • Surfaces of diffuse reflection
  • Opaque materials and transparency
  • Colors and how they're absorbed and reflected

7 Lessons in Chapter 22: Holt Physical Science Chapter 22: The Nature of Light
Electromagnetic Waves: Definition, Sources & Properties

1. 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.

The Nature of Light: Origin, Spectrum & Color Frequency

2. 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.

The 7 Major Regions of the Electromagnetic Spectrum

3. 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.

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.

Diffuse Reflection: Definition, Examples & Surfaces

5. Diffuse Reflection: Definition, Examples & Surfaces

This lesson explores the law of reflection and how it applies to different surfaces and wave types. We'll learn the difference between specular and diffuse reflection and investigate how diffuse reflection affects our perception of sound and light.

Transparent and Opaque Materials in Electromagnetic Waves

6. 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.

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.
