"WebbInfrared radiation was discovered by William Herschel in 1800. He was studying the heating effect of different colours of light by using a prism to produce a spectrum of colours and thermometers to measure their heating effect. He noticed that the heating effect got stronger as he went from the blue end of the spectrum to the red. " - Infrared light wikipedia

Webb13 okt. 2024 · One study notes that the Red (633nm) penetration is about 3.5mm, the Near-Infrared 820nm penetrates to 8mm, and 10,600nm (10.6 microns) is only 20μm. So, we could say that Near-Infrared light has about 400 times more penetration than Far-Infrared wavelengths. WebbBy definition, visible light is the part of the EM spectrum the human eye is the most sensitive to. Visible light (and near-infrared light) is typically absorbed and emitted by electrons in molecules and atoms that move from one energy level to another. This action allows the chemical mechanisms that underlie human vision and plant photosynthesis.
