About This Chapter

Watch online natural science video lessons and take the quick quizzes to measure your understanding. Learn about the different aspects of waves, sound and light.

Waves, Sound and Light - Chapter Summary and Learning Objectives

Do you know how light and sound work? Are you aware of the different types of sound and light waves? If you are not quite sure about the answers to these questions, then this chapter is for you. These lessons will discuss the ideas of vibrations and waves. You'll learn about how different wavelengths produce different types of sound and light. Some of the other things you will learn include:

  • The definition of sound
  • The categories in the electromagnetic spectrum
  • Color in light
  • Snell's law
  • The Doppler effect
  • Wave-particle duality

The Nature of Light: Origin, Spectrum & Color Frequency

1. The Nature of Light: Origin, Spectrum & Color Frequency

This lesson introduces the basics of visible light and color. Learn how the visible light spectrum is divided into the six color ranges. We'll also discuss why different people name colors in different ways.

Reflection: Angle of Incidence and Curved Surfaces

2. Reflection: Angle of Incidence and Curved Surfaces

How do waves reflect off of surfaces? How do we account for the images that we see reflected in various objects? Discover the answers to these questions as we investigate the rays and angles defining the law of reflection.

Diffuse Reflection: Definition, Examples & Surfaces

3. Diffuse Reflection: Definition, Examples & Surfaces

This lesson explores the law of reflection and how it applies to different surfaces and wave types. We'll learn the difference between specular and diffuse reflection and investigate how diffuse reflection affects our perception of sound and light.

Resonance: Definition & Transmission of Waves

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!

Transparent and Opaque Materials in Electromagnetic Waves

5. Transparent and Opaque Materials in Electromagnetic Waves

What makes an object transparent or opaque? How does light pass through some objects and not others? And what about the other types of electromagnetic waves? We'll investigate all these questions in this lesson about the transparency and opacity of materials.

Color: White Light, Reflection & Absorption

6. Color: White Light, Reflection & Absorption

What gives color to objects? How do light waves interact with materials to produce red and green or white and black? In this lesson, learn how white light is composed of all colors and how absorption and reflection influence our color perception.

Refraction & Dispersion: Definition, Snell's Law & Index of Refraction

7. Refraction & Dispersion: Definition, Snell's Law & Index of Refraction

Refraction explains why light bends in water. But, did you know that mathematical laws determine exactly how light waves are bent? In this lesson, we'll explore the mechanics of wave refraction, including Snell's Law and the index of refraction.

Diffraction: Relation to Sound & Light and Effects of Wavelength

8. 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

9. 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

10. 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.

Wave-Particle Duality: Concept, Explanation & Examples

11. Wave-Particle Duality: Concept, Explanation & Examples

Is light a particle with mass and substance? Or, is it just a wave traveling through space? Most scientists say light is both a particle and a wave! Find out how they came to this strange conclusion as we learn about the theory of wave-particle duality.
