Thermal imaging relies on detecting electromagnetic radiation from which part of the spectrum?

Answer 1

Infra-red

Answer 2

Thermography, or thermal imaging, is a type of infrared imaging. Thermographic cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 900–14,000 nanometers or 0.9–14 µm) and produce images of that radiation. Since infrared radiation is emitted by all objects based on their temperature, according to the black body radiation law, thermography makes it possible to "see" one's environment with or without visible illumination.

The amount of radiation emitted by an object increases with temperature, therefore thermography allows one to see variations in temperature (hence the name). When viewed by thermographic camera, warm objects stand out well against cooler backgrounds; humans and other warm-blooded animals become easily visible against the environment, day or night.

As a result, thermography's extensive use can historically be ascribed to the military and security services.

Answer 3

Heat (thermal energy) comes from the vibration of molecules. Molecules vibrate around the infrared range. So, thermal imaging detects radiation in the infrared range. This is just below human vision as far as frequency goes.

Answer 4

Infrared.

Answer 5

all of them. in hardship-free words a fragment of the spectrum is translated via the optic nerve into useable mind signals - this small volume is named the seen spectrum. something else of the enter receives dumped via the mind as ineffective concepts.

Answer 6

Infrared (wavelength >700nm)

Answer 7

infrared

Answer 8

infrared

Answer 9

it's infrared.
