About This Chapter
Basics of Waves - Chapter Summary
In this chapter, you'll review the basics of waves. Topics covered here include the wave parameters of speed, period, amplitude, frequency and wavelength, plus the difference between transverse and longitudinal waves. Our lessons also cover vibrations and waves, energy and motion, and the different types of waves. This chapter is designed to help you:
- Identify the uses for sound waves
- Describe the relationship between sound perception and sound wave properties
- Differentiate between Wien's Law and the Stefan-Boltzmann Law
- Outline the sources of electromagnetic waves
- Define electromagnetic radiation
- Discuss the formula for length contraction
- Explain refraction and reflection of light
- Describe curved surfaces, diffusion and angle of incidence
Work at your own pace as you complete these learning materials, and review these lessons as many times as you need to. Our video lessons can be easily navigated using the video tabs feature in the Timeline. Before or after working through the lessons, take the multiple-choice quizzes to ensure you're on the right track. These tools are accessible on your mobile device or computer 24 hours a day for your convenience.
1. 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.
2. Transverse & Longitudinal Waves: Definition & Examples
What comes to mind when you think of a wave? Chances are your mental image takes the form of a transverse wave. But, longitudinal waves are just as important, and understanding the difference is vital to learning about waves. In this lesson, explore both types of waves and the unique characteristics of each.
3. Vibrations and Waves: Energy and Motion
What is a wave? What causes waves, and how do they travel from one place to another? This lesson will guide you through the basics of waves. We'll discuss their origins from vibrations and investigate how they carry energy through a medium.
4. Waves: Types & Definition
Examine the different types of waves and what parts of our daily lives are affected by waves, from the ocean to the microwave to sound. Explore how waves are measured and classified.
5. What are Sound Waves? - Definition, Types & Uses
This lesson will explain what sound waves are, discuss features of sound waves, and provide some examples and uses they have in everyday life. A short quiz will follow.
6. Relationship Between Sound Wave Properties & Sound Perception
After completing this lesson, you will be able to describe the properties of sound waves and explain how they relate to what you hear when you listen to a sound. A short quiz will follow.
7. What Are Wien's Law & the Stefan-Boltzmann Law?
This lesson will explain why an object glows and why it changes color with temperature as we take a look at blackbodies, electromagnetic radiation, Wien's Law, and the Stefan-Boltzmann Law.
8. Electromagnetic Waves: Definition, Sources & Properties
In this lesson, learn the basics of electromagnetic waves and how they make up the electromagnetic spectrum. We will explore the major trends and categories within the spectrum, as well as the various sources of electromagnetic waves.
9. What is Electromagnetic Radiation? - Wavelength, Spectrum & Energy
Light, microwaves, X-rays, and cell phone transmissions are all examples of electromagnetic radiation. Read more about this fascinating, mostly invisible phenomenon that has been harnessed by humans for so many purposes. A quiz is included.
10. Length Contraction Explained: Formula & Example
Learn what length contraction has to do with the speed of light, and why we don't notice it in every day life. Also learn a little about other relativity topics that will help you understand length contraction better.
11. Reflection & Refraction of Light: Physics Lab
This lesson examines what reflection and refraction are and demonstrates how they work using experimentation. You'll be provided with step-by-step instructions on how to complete the experiments, as well as have the ability to complete a short quiz.
12. Reflection: Angle of Incidence, Curved Surfaces & Diffusion
How does light bounce off surfaces? Learn the differences between how light bounces off flat surfaces, curved surfaces, and non-shiny surfaces. Then reflect on your reflection knowledge with a quiz.
