WebInfrared radiation (IR), also known as thermal radiation, is that band in the electromagnetic radiation spectrum with wavelengths above red visible light between 780 nm and 1 mm. IR is categorized as IR-A (780 nm-1.4 µm), IR-B (1.4-3 µm) and IR-C, also known as far-IR (3 µm-1 mm). Common natural sources are solar radiation and fire. WebDec 12, 2016 · Different wavelengths have different absorption ratios in the same materials. The typical example is a plastic bag, which is transparent to visible light, but opaque to infrared light. This means that it mostly lets visible light through (no absorption, no heating), while capturing infrared light (absorption, heating).
