About This Chapter
Mirrors & Lenses in Geometric Optics - Chapter Summary
Review the fundamentals of mirrors and lenses in geometric optics with this comprehensive online physics chapter. As you progress through this series of short and informative lessons, you'll study different mirror types, Snell's law, ray tracing and a variety of mirror and lens equations. After completing each lesson, try the accompanying self-assessment quiz to practice solving mirror and lens problems on your own. If you get stuck or need any extra help, simply submit your questions to our instructors online. The chapter is also accessible on any device that that has an Internet connection. When you're finished with the chapter, you should be able to:
- Differentiate between plane and spherical mirrors
- Explain ray tracing with convex mirrors, concave mirrors and reflected images
- Answer mirror and lens questions using applicable equations
- Evaluate lenses and ray diagrams
- Define the thin lens equation
- Summarize Snell's law
- Understand total internal reflection and the components of fiber optic cables
1. 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.
2. Ray Tracing: Convex & Concave Mirrors
There are three types of mirrors: plane, convex and concave. Convex and concave mirrors are curved. In this lesson, we will explore how to determine where images are in plane, convex and concave mirrors.
3. Using Equations to Answer Mirror Questions
After watching this lesson, you will be able to answer questions on mirrors, stating whether an image is real or virtual, upright or inverted, and larger or smaller. A short quiz will follow.
4. Ray Diagrams & Lenses: Physics Lab
After completing this lab, you will be able to explain how lenses work, explain the difference between convex and concave lenses, draw ray diagrams to analyze the image produced by a lens, and apply that understanding to eyeglasses.
5. Thin Lens Equation: Examples & Questions
After watching this lesson, you will be able to explain what a lens is (both concave and convex), list uses of lenses in everyday life, and use the thin lens equation to solve problems. A short quiz will follow.
6. Using Equations to Answer Lens Questions
After watching this video, you should be able to use equations to answer lens questions, including figuring out whether the image produced by a lens is real or virtual, bigger or smaller, and upright or inverted. A short quiz will follow.
7. What is Snell's Law?
What happens when light travels from one medium to another, like from air to water? The answer can be described by Snell's Law, which is the main focus of this lesson.
8. Total Internal Reflection & Fiber Optic Cables
Fiber optic cables can transmit light very quickly over large distances. How exactly do they work and what does this have to do with total internal reflection? In this lesson, learn the answers to these questions and more!
