Infrared is a form of light that falls just outside the visible spectrum… light that we can not see with our eyes, but that we can sometimes feel on our skin as heat.The world around us looks remarkably different in infrared light. People become luminous objects as we see things by the glow of their heat rather than the light that falls upon them.
The Cool Cosmos website from Cal Tech University explores the many fascinating ways infrared light and photography is used in astronomy, medicine, and day to day life. There are complete lesson plans, printouts and other teaching resources here too. Be SURE to check out the “Infrared Gallery”. Fascinating!
