About This Chapter

Watch our lessons and review how sound waves function as you prepare for the MTEL Physics exam. These video lessons offer information that will help you with these types of questions on the exam.

MTEL Physics: Sound Waves & Principles of Acoustics - Chapter Summary

Let the lessons in this chapter assist you with information on the principles of sound as you prepare to take the MTEL Physics test. After viewing the videos, you'll be ready to answer questions on these topics on test day:

  • How sound is defined
  • Factors that influence the speed of sound
  • Wave parameters
  • Volume and pitch in sound waves
  • The definition and applications of the Doppler effect
  • Interference patterns of sound waves
  • Resonance of sound and light waves

You can complete a short practice quiz after you finish each lesson. If you miss any questions, use the video tags to track down related video segments for additional review, or look over the lesson transcript.

6 Lessons in Chapter 16: MTEL Physics: Sound Waves & Principles of Acoustics
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.

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

2. 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.

Pitch and Volume in Sound Waves

3. 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.

The Doppler Effect: Definition, Examples & Applications

4. 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.

Interference Patterns of Sound Waves

5. Interference Patterns of Sound Waves

Sounds are all around us, but how they interact affects how we experience them. In this lesson, we'll explore the patterns created by interfering sound waves. Afterward, you can test your understanding with a brief quiz.

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!
