# Ch 5: Properties of Waves

Use our video lessons and quizzes to help you understand wavelength, amplitude, period, frequency and speed. Learn how to identify these wave parameters and determine factors affecting a wave's speed, volume or pitch.

## Properties of Waves - Chapter Summary

This chapter's introductory lessons explain the causes of waves and illustrate how they transfer energy across a medium. The five parameters of waves are also discussed. Watch as instructors show you how to use a wave's amplitude to measure its energy or demonstrate why calculations involving frequency and wavelength can determine its speed. You'll also get to study the differences between transverse and longitudinal waves, and many of the lessons discuss the characteristics of sound. For example, you could learn about factors influencing the speed, intensity and volume of sound waves, or examine the ways in which wave frequency determine pitch.

Other lessons explain how a change in the position of a wave source affects the apparent frequency of sound and light waves, otherwise known as the Doppler effect. You can also look at evidence explaining the theory of wave-particle duality, which holds that light is both a wave and a stream of photons. Some of the main ideas addressed in this chapter include:

• Wave parameters
• Transverse and longitudinal waves
• Factors affecting wave transmission

Once you've finished following the illustrations and examples included in these short videos, you can use the transcripts to view key terms at a glance and click on the video tags to go over main points discussed by the instructors. Additionally, each lesson has a self-assessment quiz that you can take as often as needed to make sure your proficiency level is where you need it to be.
