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. 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.
3. Diffuse Reflection: Definition, Examples & Surfaces
This lesson explores the law of reflection and how it applies to different surfaces and wave types. We'll learn the difference between specular and diffuse reflection and investigate how diffuse reflection affects our perception of sound and light.
4. 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.
5. 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.
6. 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.
7. 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.
8. Polarization of Light & Malus's Law
After watching this video, you will be able to explain what polarization of light is, list a number of examples of how polarization of light is used, state Malus's Law, and use it to solve problems involving the intensity of light through a polarizer.
9. Polarization by Reflection & Brewster's Law
After watching this lesson, you will be able to explain what polarization by reflection is, give a few examples of polarization in everyday life, explain Brewster's Law descriptively and use the equation to solve problems. A short quiz will follow.
