- Describe the theory of the standing wave
- Exhibit knowledge of pitch and volume in sound waves
- Discuss resonance and the transmission of waves
- Showcase an understanding of the Doppler effect and how to calculate the frequency 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.
2. 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.
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.
4. 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!
5. The Doppler Effect: Formula & Calculation
The Doppler effect causes wave frequencies to change when the source of the waves is moving. In this lesson, learn about the Doppler effect and how to calculate the frequency of sound produced by a moving source.
