About Infrared
Wavelength: 700nm-1mm
Frequency: 430Thz-300Ghz
Velocity in a Vacuum: 300,000,000m/s
Facts:
-Infrared is a thermal type of wave
-There are things infrared light can see through that visual light can't and vice versa
-In WW2 sharpshooters used infrared to see their enemies during the night
Everyday Uses
Two uses for infrared:
-night vision
-remote controls
Health Impacts
-It helps save people who are lost by using their body heat to find them
-Over exposion to eyes can lead to corneal ulcers and retinal burns
Vampire bats now are able to detect heat signatures of things. They have been using this to find where vains are more likely to be at within animals. Scientist are studing Vampire bats right now and more related to horses than rats. Vampire bats gained this ability through evolution over time to help them survive better to get food easier, though bats that eat fruits and insects don't have this ability.
