What is Infrared Light and What does it tell us?
  • Infrared light is a form of electromagnetic
    radiation, one that is invisible to our eyes.
  • Infrared light is what we commonly think of as
    heat
  • Infrared light is emitted by anything in the
    universe with a temperature (above absolute
    zero).
  • Objects below 1,000 degrees C radiate mostly in
    the infrared.

Properties of Infrared Light
  • Infrared light can pass through many things that
    block visible light, like smoke and dust (and
    most plastics).

    visible light through (like our atmosphere!)
