    You know it when you see it, or when you don\u2019t. But ask any two people to define light, and unless they\u2019re schooled in Physics, you\u2019ll probably get some really basic answers, as in \u201cIt\u2019s that thing that comes from the sun and makes everything, you know\u2026not dark\u201d. But like everything in Nature, light has a composition. It has a structure, an anatomy that can be broken down into parts. And it matters because without light, we would have no way to perceive color.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    Light doesn’t just come out of nowhere. All light has a source. Some sources of light are artificial, like lamps and spotlights. But the biggest natural light source known to our species is “Sol”\u2026the technical name for our Sun. We get the bulk of our light from the Sun. We call that natural lighting “ambient” light. Ambient light is the light that’s visible when all artificial sources of light are turned off.<\/span><\/p>

    Most of us learned in school that light travels travels really fast at 186,000 miles per second. But exactly HOW does it travel? Light “radiates”, traveling away from its source through space. Light travels in the form of beams that we call \u201crays\u201d. It doesn\u2019t bend or turn corners. Light travels in a straight line. But if we could take an X-Ray of light, what would it look like? Well, it looks like a spectrum.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    We use a prism to act as our X-Ray. Before we came up with that device, the only way we even knew there was a spectrum was because Nature provided us with the atmospheric conditions required to see a rainbow. The prism gave us our first controlled look at the anatomy of light. Light may look white to the naked eye, but the prism shows us what light really looks like\u2026on the inside. We call that arrangement of color a Spectrum.<\/span><\/p>

    This spectral view of light tells us all kinds of things about its anatomy. We call this rainbow the \u201cvisible\u201d spectrum\u2026the portion of the spectrum that can actually be perceived by the human eye. The prism shows us the visible spectrum when we aim it at the sun and let natural light shine through it. It isn\u2019t the full spectrum. The “invisible” spectrum includes ultraviolet and infrared light, which the naked eye cannot perceive but it’s very definitely there. The visible spectrum also doesn\u2019t show us all the colors the human eye can perceive. That’s because some colors are are created by mixing. We’ll talk more about this when we get into the subject of primary, secondary, and tertiary colors.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
