About This Chapter
Light, Mirrors & Lenses - Chapter Summary
In this chapter, our instructors will define the concept of rectilinear propagation of light and provide examples to help you understand the topic. A physics lab lesson will show you how to set up experiments that illustrate both refraction and reflection of light.
As you move through the lessons, you will review two different kinds of mirrors and be able to explain what a mirror does and how it works. This chapter will help you:
- Define rectilinear propagation of light
- Complete experiments using the concepts of refraction and reflection of light
- Differentiate between plane mirrors and spherical mirrors
- Explain how the lens of the eye functions to give you vision
If you have questions as you review this chapter, contact an instructor for help. Use the video tabs feature in the Timeline to jump directly to a section in a video lesson you'd like to review. You can use the printable transcripts that accompany each lesson to study the material offline at any time. Each lesson is designed to be easy to understand.
1. Rectilinear Propagation of Light: Definition & Examples
A light source emits light rays in all directions. In this lesson, we'll learn how specifically light travels and compare it to the motion of other objects.
2. 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.
3. 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.
4. 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.
