Ch 19: Properties of Mechanical Waves

About This Chapter

Let us help you boost your understanding of mechanical waves, their properties and the transmission of waves with this chapter. Use these lessons and quizzes as a comprehensive study guide as you prepare for a test or homework assignment.

Properties of Mechanical Waves - Chapter Summary

In this chapter, our instructors define transverse and longitudinal waves and include examples. How to measure waves using the five wave parameters is also covered. You will learn about how waves interact with each other using constructive and destructive interference.

As you progress through the chapter, the Doppler Effect and how it changes light and sound is presented. The concepts of resonance and diffraction are introduced, as are standing waves, the waves that are responsible for musical notes. After you review this chapter, you should have the knowledge necessary to:

  • Give examples of transverse and longitudinal waves
  • Measure and describe waves using five wave parameters
  • Define constructive and destructive wave interference
  • Explain how the Doppler Effect affects our perceptions of sound and light
  • Describe how the principle of resonance affects sound and lights
  • Outline how diffraction relates to the wavelength of a wave
  • Detail standing waves

Before or after reviewing the video lessons, use the quizzes and chapter tests to discover how well you understand the material. If you need to review just one portion of a video, use the video tabs in the Timeline to jump directly to the section you'd like to re-watch. Each lesson is accompanied by a printable transcript so you make a copy to study at any time. Our mobile-friendly lessons are designed by professional instructors to ensure your learning experience is fun and engaging.

Transverse Wave: Definition, Parts & Examples

1. Transverse Wave: Definition, Parts & Examples

This lesson will define transverse waves, discuss the names for various features and parts of a transverse wave, and go through some examples of transverse waves in the world. A short quiz will follow.

Longitudinal Wave: Definition, Parts & Examples

2. Longitudinal Wave: Definition, Parts & Examples

There are a few different kinds of waves, including the longitudinal wave. This type of wave occurs when the particles of a medium move in the same direction as the wave itself.

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.

Constructive and Destructive Interference

4. 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.

The Doppler Effect: Definition, Examples & Applications

5. The Doppler Effect: Definition, Examples & Applications

What is the Doppler effect? How does it affect our perceptions of sound and light? In this lesson, learn how traveling wave sources can change the way we observe sound and light waves. Explore the applications of the Doppler effect on shock waves, sonic booms, and the movements of distant galaxies.

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!

Diffraction: Relation to Sound & Light and Effects of Wavelength

7. 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.

Standing Wave: Definition, Equation & Theory

8. Standing Wave: Definition, Equation & Theory

In this lesson, you'll learn about the kind of waves that are responsible for our experience of musical notes. These waves are called standing waves. Learn what makes them unique and how they represent the notes we hear.
