PRESENTATION OUTLINE
1.
HOW DO INFRARED SCOPES WORK?
BY JAY SHORT AND ISAAC BIELECKI
2.
HOW IS THE WAVE IS CREATED?
Infrared light is created by thermal, or heat, energy.
These waves are not visible to the human eye.
3.
HOW ARE INFRARED WAVES USED IN REAL LIFE?
They're used in:
Computers
Remote controls
Optics( military and hunting scopes)
4.
CAN INFRARED LIGHT BE DANGEROUS?
Infrared light is harmless to humans unless it's highly concentrated on a single object
A laser is a common source that can damage people's eyes who look directly at the light
5.
WAVELENGTH AND FREQUENCY
Wavelenth= 750nm - 1mm (about the size of an ant)
Frequency= 430THz - 300GHz
6.
HOW INFRARED SCOPES FUNCTION:
Infrared scopes are equipped with electronics that allow humans to see lower frequencies when looking through them
They take infrared light, and change it into visible light that humans can see
7.
FUN FACT
Without infrared light, Seal Team Six wouldn't have been able to kill Osama Bin Laden. Attacking at night allowed them to be virtually invisible, but they used infrared waves to see the enemy. Without infrared light, we may have had another 9/11.
