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. Light and Relativity: Breakdown of Classical Relativity with Light Example
The speed of light is constant regardless of the source of the light or the position of the observer. However, the components of speed - distance and time - are relative to speed. This lesson uses examples to explain how the relativity of distance and time accounts for the constant speed of light.
3. The 7 Major Regions of the Electromagnetic Spectrum
This lesson will walk you through each of the major regions of the electromagnetic spectrum. Explore the unique characteristics of X-rays, microwaves, radio waves, UV rays, infrared, gamma rays, and of course, visible light.
4. Transparent and Opaque Materials in Electromagnetic Waves
What makes an object transparent or opaque? How does light pass through some objects and not others? And what about the other types of electromagnetic waves? We'll investigate all these questions in this lesson about the transparency and opacity of materials.
5. 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.
6. 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.
