About This Chapter
Waves & Optics- Chapter Summary
This chapter will help you review the main ideas, concepts and theories behind waves and optics. Having knowledge on waves, lenses and light will help you learn more complex topics in the future. By the end of the chapter, you will have covered the following topics:
- Six color ranges
- Five wave parameters and how they characterize waves
- Unique characteristics of electromagnetic waves
- Two types of waves and their differences
- How mechanical waves are produced
- Concepts of waves such as scattering, diffraction and reflection
- Properties of sound waves
- Application of the Doppler effect
- How images are produced on mirror
- White light's interaction with a prism
- Concave and convex lenses
- Function of lenses
These bite-size lessons are broken down for you by our professional instructors. You have the opportunity to test your knowledge by taking our lesson quizzes. You will get the results for the quiz right away, and we make it easy to go back into the lesson and review concepts again. There is also a chapter exam that allows you to test yourself on everything that is covered in the chapter. This ensures you have mastered the material, and you are ready to move forward.
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.
2. 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.
3. What are Electromagnetic Waves: Definition & Types
Explore electromagnetic (EM) waves, their features and how they differ from other waves. Learn how EM waves are organized on a spectrum based on the amount of energy they produce, from radio waves to gamma rays.
4. 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.
5. Mechanical Waves: Production & Propagation
What is a mechanical wave? Learn about the types of mechanical waves, how they are produced, and what affects their propagation, then test yourself by taking a quiz.
6. Wave Phenomena: Definition & Examples
In this lesson, you will learn about the four basic behaviors, or phenomena, that can be observed when studying waves. These four behaviors are reflection, interference, refraction, and diffraction.
7. 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.
8. 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.
9. Mirrors: Difference Between Plane & Spherical
After watching this lesson, you will be able to explain what a mirror is and how plane mirrors and spherical mirrors are different, including the images they produce. A short quiz will follow.
10. What is a Prism? - Definition & Refraction
In this lesson, you'll learn about the prism and what prisms do to white light. You'll explore the properties of light waves, as well as the concept of refraction, which causes white light to bend in a prism and spread out into the different spectrum of colors.
11. Lens Types: Simple, Compound & Other Types
In this lesson we will explore what a compound lens is versus a simple lens as well as what it means for a lens to be concave or convex and how these particular lens shapes can be used to correct certain visual impairments.
12. Lens of the Eye: Definition & Function
The lens of the eye focuses light and allows you to see. In this lesson, you will learn what the lens is made of and how it changes shape so that you can have clear vision.
