About This Chapter
Properties of Light - Chapter Summary
The lessons in this chapter provide an overview of the properties of light. You'll review Snell's law and index of refraction, three-dimensional solids, and the law of reflection. You'll also look at how to calculate the angle of reflection and the angle of incidence. After completing the chapter, you should be prepared to:
- Explain what light is and discuss the different kinds of light
- Describe how mathematical laws determine refraction
- Discuss the law of reflection and different types of reflection
- Explore the difference between a compound lens and a simple lens
- Detail how a triangular prism is formed
- Define frustrated total internal reflection
These lessons help you quickly get up to speed on the properties of light. Vocabulary words are highlighted in bold for quick reference. You can use the Help feature to submit questions to instructors if you get stuck on a topic. Video timelines let you easily navigate to specific topics. Each lesson is also accompanied by a full written transcript.
1. What is Light?
This lesson will define and describe what light is from both technical and more common-use perspectives, discuss what the different kinds of light are, and explain why it's called radiation.
2. Refraction & Dispersion: Definition, Snell's Law & Index of Refraction
Refraction explains why light bends in water. But, did you know that mathematical laws determine exactly how light waves are bent? In this lesson, we'll explore the mechanics of wave refraction, including Snell's Law and the index of refraction.
3. Angle of Reflection: Definition & Formula
When light hits an object, it bounces off the object's surface and reaches our eyes. All that we see around us is made possible by a phenomenon called reflection. This lesson covers the definition, angle, types of reflection, and the law of reflection.
4. 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.
5. What is a Triangular Prism? - Definition, Formula & Examples
Triangular prisms are three-dimensional solids formed by putting rectangles and triangles together. In this lesson, learn how to find the size inside (volume) and outside (surface area) of a triangular prism.
6. Frustrated Total Internal Reflection
Under certain conditions light that should be reflected in total internal reflection can be refracted instead. This process is known as frustrated total internal reflection, and in this lesson we will learn how it works.
