WebIR radiation extends from the red edge of the visible spectrum of light across a wavelength range of between 700 – 1,000,000 nanometers (nm). There are four distinct wavebands within that spectrum: near-infrared (NIR), MWIR, SWIR, and LWIR. How objects reflect or emit IR radiation is indicative of a number of physicochemical and thermal ... WebUV and IR - Key takeaways. Ultraviolet (UV) radiation is electromagnetic radiation between the violet part of visible light and X-rays on the EM spectrum. UV radiation has wavelengths between 100-380nm and is emitted from the sun's surface. Infrared (IR) radiation is between the red part of visible light and microwaves on the EM spectrum.
