Ch 8: Nature of Sound Waves

About This Chapter

These fast, fun lessons are designed to help you review concepts related to the nature of sound waves. There are also short quizzes after each lesson that allows you to practice for an exam.

Nature of Sound Waves - Chapter Summary

This chapter helps you understand information about sound waves. You will learn about how sound travels, the relationship between pitch and volume, the main factors that affect the speed of sound, and how sound waves are sent to the brain. Through these lessons, you will:

  • Explore how sound changes volume
  • Describe the different properties of sound waves
  • Identify the uses of ultrasonography
  • Explain the different types of reflection
  • Understand how sound and light are affected by resonance

The video lessons are all accompanied by video tags that allow you to jump around the lesson to areas you want to focus more on. The lesson transcripts are complete with terms and phrases in bold for emphasis so it is easier for you to find the areas that you need to focus on when studying. All of the resources in this chapter are mobile friendly, so you can take advantage of these resources at home or away, as long as you have a reliable Internet connection.

What is Sound? - Definition and Factors Affecting the Speed of Sound

1. What is Sound? - Definition and Factors Affecting the Speed of Sound

Explore the minute workings of sound waves and how they travel. We'll discuss the main factors that affect the speed of sound waves, and we'll try some mathematical problems involving the wave equation.

Pitch and Volume in Sound Waves

2. Pitch and Volume in Sound Waves

What do pitch and volume mean when talking about sound waves? Further your understanding of sound waves in this lesson as we explore the more familiar aspects of sound. We'll learn about pitch and volume and how they relate to sound wave parameters.

Sound Attenuation: Definition & Effects

3. Sound Attenuation: Definition & Effects

What exactly is sound, how does it travel, and why does it change volume? There are a lot of questions we can ask about sound, and in this lesson, we'll explore the idea of sound attenuation to explain a few of them.

Mechanics of Hearing & How the Brain Processes Sound

4. Mechanics of Hearing & How the Brain Processes Sound

How do our ears transform sound into signals that our brains can process? In this lesson, you'll cover properties of sound waves and how they interact with key parts of the ear.

What Is Ultrasonography? - Definition, History & Uses

5. What Is Ultrasonography? - Definition, History & Uses

Ultrasonography is a diagnostic medical procedure that uses sound waves to produce images on a screen, which allows medical providers to view internal structures of the body. In this lesson, you'll learn more about ultrasonography and its uses.

Reflection of Waves: Definition & Examples

6. Reflection of Waves: Definition & Examples

This lesson will define reflection in the context of waves, summarize the types of reflection, and provide examples of reflection in action. A short quiz will follow.

Resonance: Definition & Transmission of Waves

7. 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!
