thermal imaging test

?
what does thermal imaging use in the electromagnetic spectrum?
infrared
1 of 7
Emissivity is a term representing a material's ability to emit
thermal radiation
2 of 7
A black body is a theoretical object which will radiate infrared radiation at its contact temperature. If a thermocouple on a black body radiator reads 50 °C, the radiation the black body will give up will be
50
3 of 7
IR film is sensitive to infrared (IR) radiation in the 250°C to 500°C range, while the range of thermography is approximately -50°C to over 2,000°C. So, for an IR film to work thermographically, it must be over 250°C or be reflecting infrared radiati
hot
4 of 7
All objects above the absolute zero temperature (0 K) emit
infrared radiation
5 of 7
It shows a visual picture so temperatures over a large area can be
compared
6 of 7
Images can be difficult to interpret accurately when based upon certain objects, specifically objects with erratic temperatures, although this problem is reduced in active
thermal imaging

I was so **** I had to give up, this was life-destroying Liam.
