What do quantum mechanics and global warming have to do with each other? More than you might think. Surprisingly, this video explains how it's not the energy emitted from the sun that causes the problem, but how the infrared radiation...

Photo reactive paper is used to do art! You can order this type of paper, have learners place objects on it, and then set it out in the sunlight for a few minutes to create a print. A chemical reaction occurs, driven by light, to turn...

This video segment adapted from NASA's Goddard Space Flight Center gives a detailed explanation of the catalytic chemical process that has led to the creation of the ozone hole. [5: 04]

In order to understand how we study the universe, we need to talk a little bit about light. Light is a form of energy. Its wavelength tells us its energy and color. Spectroscopy allows us to analyze those colors and determine an object's...

Provides an introduction to light and the electromagnetic spectrum, and how light behaves as both a wave and a particle. [9:36]

Light and electromagnetic radiation are introduced by Khan Academy. [9:37]

In the following video Paul Andersen details the waves in electromagnetic radiation. There is an inverse relation between the wavelength and frequency of electromagnetic waves. Electromagnetic radiation includes gamma rays, x-rays,...

This lesson will introduce you to the anatomy and physiology of the human visual system, its connection to the brain and how this system processes light. It is 2 of 3 in the series titled "How We See."

This lesson discusses the light spectrum and its influence on living things. It is 1 of 3 in the series titled "Radiation and Energy."

To understand light you have to know that what we call light is what is visible to us. Visible light is the light that humans can see. Other animals can see different types of light. Dogs can see only shades of gray and some insects can...

A video defining x-rays. [1:50]

In this video, Paul Andersen describes some of the properties of electromagnetic radiation. The electromagnetic spectrum varies by wavelength from radio waves to gamma rays. We only see a portion of the spectrum known as visible light. A...
