WebFeb 27, 2024 · Another advantage of IR radiation is that its longer wavelength means it doesn't scatter as much as visible light, according to NASA. Whereas visible light can be … Near infrared radiation is not related to the temperature of the object being photographed – unless the object is very, very hot. Infrared film 'sees' the object because the Sun (or some other light source) shines infrared light on it and it is reflected or absorbed by the object. See more Different surfaces You can see that dull surfaces are good absorbers and emitters of infrared radiation. Shiny surfacesare poor absorbers and … See more Gold is being used as reflector material for infrared heat lamps because gold offers the highest reflectivity of any material in the infrared spectrum. A thin layer of gold directly on the back … See more Reflected near-infrared radiation can be sensed by satellites, allowing scientists to study vegetation from space. Healthy vegetation absorbs … See more The surface of aluminum has the ability NOT TO ABSORB, but TO REFLECT 95% of the infrared rayswhich strike it.
