# Ch 12: Waves Overview

Use the following video lessons and quizzes to learn about various types of waves, including sound and electromagnetic waves. Also, learn about the nature of light, as well as refraction and dispersion.

## Waves Overview - Chapter Summary

This online chapter can teach you about transverse and longitudinal waves, as well as factors that affect the speed of sound. Our brief video lessons also can introduce you to the seven major regions of the electromagnetic spectrum and show you the difference between constructive and destructive interference. Some of the additional topics you'll encounter in this chapter on waves include the following:

• The origin, spectrum and color frequency of light
• Reflection: angle of incidence and curved surfaces
• Resonance: definition and transmission of waves
• Transparent and opaque materials in electromagnetic waves
• White light and reflection and absorption of color
• Refraction and dispersion: Snell's law and the index of refraction
• Diffraction: relation to sound and light and effects on wavelength
• The Doppler effect
• Wave-particle duality
• Wave parameters: wavelength, amplitude, period, frequency and speed

To get the most from this chapter on waves, take advantage of all three components of each lesson: the video, the transcript and the self-assessment quiz. The videos feature tags that can take you to their main points if you just need a quick review, while many of the transcripts feature links to some of our other articles if you desire a more in-depth study option. Finally, take the self-assessment quizzes to show you where you've mastered the material and where you could use a bit more study time.
