Ch 20: Holt Physical Science Chapter 20: The Energy of Waves

About This Chapter

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

How it works:

  • Identify the lessons in the Holt Physical Science Energy of Waves chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the waves-related 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:

  • Vibrations and waves
  • Transverse and longitudinal waves
  • Wave parameters
  • Reflection, diffraction, refraction and dispersion
  • Constructive and destructive interference
  • Resonance and transmission of waves

6 Lessons in Chapter 20: Holt Physical Science Chapter 20: The Energy of Waves
Vibrations and Waves: Energy and Motion

1. Vibrations and Waves: Energy and Motion

What is a wave? What causes waves, and how do they travel from one place to another? This lesson will guide you through the basics of waves. We'll discuss their origins from vibrations and investigate how they carry energy through a medium.

Transverse & Longitudinal Waves: Definition & Examples

2. Transverse & Longitudinal Waves: Definition & Examples

What comes to mind when you think of a wave? Chances are your mental image takes the form of a transverse wave. But, longitudinal waves are just as important, and understanding the difference is vital to learning about waves. In this lesson, explore both types of waves and the unique characteristics of each.

Wave Parameters: Wavelength, Amplitude, Period, Frequency & Speed

3. Wave Parameters: Wavelength, Amplitude, Period, Frequency & Speed

How do we measure and describe waves? How do waves differ based upon their shapes? This lesson will guide you through the five wave parameters - period, frequency, amplitude, wavelength, and speed - that we use to characterize waves.

Diffraction: Relation to Sound & Light and Effects of Wavelength

4. Diffraction: Relation to Sound & Light and Effects of Wavelength

This lesson explores diffraction as one of the many behaviors of waves. Learn how diffraction occurs in sound and light waves and how it is affected by the wavelength of a wave. Find out how animals use diffraction to communicate and how scientists use it to study molecules.

Constructive and Destructive Interference

5. Constructive and Destructive Interference

What happens when one wave meets another? Do the waves converge to make one giant wave? Or, do they destroy each other? In this lesson, we'll explore the workings of wave interference.

Resonance: Definition & Transmission of Waves

6. Resonance: Definition & Transmission of Waves

This lesson describes how sound and light waves are affected by the principle of resonance. Learn how resonance occurs through the vibrations and resonant frequencies of objects. You'll investigate everyday examples of resonance and learn how to break a wine glass with your voice!
