WebInfrared thermography cameras allow us to use our eyes to measure the temperature of an object instead of having to risk contact with something potentially dangerous. Most objects with machinery or electronics heat up before failing, making IR cameras the perfect tool for cost-effective diagnostics in a variety of situations. WebInfrared (sometimes written infra-red or infra red) radiation was discovered by the famous astronomer, William Herschel. As happens quite often in scientific discoveries, it came from noticing something unexpected, asking questions and then carrying out more tests in order to try to find answers. In this case, he had been observing the Sun.

WebWhite and shiny silvery surfaces are the worst absorbers, as they reflect all visible light wavelengths. Poor absorbers are also poor emitters, and do not emit radiation as quickly … WebInfrared waves have longer wavelengths than visible light and can pass through dense regions of gas and dust in space with less scattering and absorption. Thus, infrared energy can also reveal objects in the universe that cannot be seen in visible light using optical … What is the visible light spectrum? The visible light spectrum is the segment of … teri youngblood obituary

Webinfrared rays can be hazardous to ocular tissue, and describes the mechanisms of cataractogenesis resulting from occupational exposure. Figure 1: Electromagnetic … WebIR-reflex assessment had significantly better sensitivity (100 vs 71%, p < 0.05) and specificity (100 vs 63%, p < 0.01) than red-reflex assessment in the diagnosis of childhood cataract. … Web~Infra-red rays are the electromagnetic wave whose wavelength is just below the red ray of the visible light. Its wavelength is 750 nm-400000 nm. ~Infra-red rays is emitted by any hot object. It can be hot iron, hot metal, fire, burning charcoal. Sun ray also has infra-red rays in it & that’s why it feels the heat. *Infrared therapy: teriyon cooper
