How Light Works
When we see an object, we are actually seeing light -- light that somehow left the object and reached our eyes. We also encounter light in things that produce it, from light bulbs, to lasers, to lightning bugs, to the sun. Learn how light waves are produced, how light travels, and how light explains the origin of color.
