Transparent material for IR?
if IR refers to Infrared light then, the most commonly used material in day to day life is the right material... Common salt-Sodium Chloride and few other chloride salts are IR -transparent.
nothing Anything that is transparent will have a refractive index. Glass is transparent to visible light and has a refractive index with it. Having these combined properties lets you make a lens for visible light out of glass. Now glass is transparent to IR radiation so any glass lens would focus IR radiation.
The bending of light as it passes into a transparent material of different optical intensity is known as?
It is a spectra that shows how transparent a material can be. in scientific terms, it is incidence of electromagnetic radiation (from the UV, Visible, Infrared wavelength regions) from a source to a material, and there is a detector which records the amount of radiation remaining after the transmission (these radiation that is gone is either reflected of the surface or absorbed by the material). The equipment that measures this is called UV-Vis-NIR spectrometer.
Even though you can see through a material..i.e. it is transparent...it may have color and a physicist will want to know this information. What type of light is hitting this material is important to include in your question as well as the type of transparent material. What type of light? (and the strength ...source would be great) What type of material? What color is the material? Answer: It allows light to pass through a material
Biological systems such as the human body are good at making transparent material, such as the aqueous humor in eyes, and they are also good at making strong inflexible material such as bone, but they are not good at making material that is both transparent and strong. Eyes have to be transparent in order to see, therefore that was the priority, rather than physical strength. Of course, we do know how to make glass, which…
Paper, while a solid material, is absorbent. It will absorb water, so it becomes transparent until it dries. Oil is a liquid that paper will absorb, only the oil does not dry in the paper. Therefore, the paper remains transparent until the oil dries. It is the same principle that secret letters are written an sent. A material that dries transparent on paper will be visible under light.
