Test your knowledge with a 30-question chapter practice test
The Nature of Light: Origin, Spectrum & Color Frequency

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.

Reflection: Angle of Incidence and Curved Surfaces

2. Reflection: Angle of Incidence and Curved Surfaces

How do waves reflect off of surfaces? How do we account for the images that we see reflected in various objects? Discover the answers to these questions as we investigate the rays and angles defining the law of reflection.

Refraction & Dispersion: Definition, Snell's Law & Index of Refraction

3. 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.

Transmission of Light: Definition & Overview

4. Transmission of Light: Definition & Overview

This lesson will explain what is meant by 'transmission of light,' discuss the ways that light can be transmitted through a medium, and also explore how light is measured.

Color: White Light, Reflection & Absorption

5. Color: White Light, Reflection & Absorption

What gives color to objects? How do light waves interact with materials to produce red and green or white and black? In this lesson, learn how white light is composed of all colors and how absorption and reflection influence our color perception.

What is a Prism? - Definition & Refraction

6. 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.

Mirrors: Difference Between Plane & Spherical

7. 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.

Using Equations to Answer Mirror Questions

8. 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.

Ray Tracing with Mirrors: Reflected Images

9. Ray Tracing with Mirrors: Reflected Images

After watching this lesson, you will be able to explain what a mirror is and use ray tracing diagrams, along with the law of reflection, to explain what you see when you look in a mirror. A short quiz will follow.

Using Equations to Answer Lens Questions

10. 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.
