SWINYER, HIPP, DAVEY

HOW THE WAVE IS CREATED

  • Objects that emit heat
  • Measured in micrometers
  • More heat=higher frequency

POSSIBLE DANGERS

  • High concentrations of this wave could lead to burns
  • Exposure to eyes may cause cornea and retina damage.

Wavelength is 10^-4 m to 10^-5 m.
This is also the size of a cell.

FUN FACTS

  • Snakes can sense warm-blooded animals with infrared sensory pits.
  • In 1986, a satellite called GOES 6 took a picture of Earth in infrared to determine which parts were clouds and which parts were the ocean.
  • Infrared Light can travel through thick smoke, dust, or fog, and even some materials.

HOW IS INFRARED LIGHT USED IN THE MEDICAL FIELD?

  • Thermographic infrared cameras that measure body tempurature.
  • Detect fevers.
  • Finds cancer.
  • Finds peripheral vascular disorders.
  • Signals diabetic neuropathy.
