WebThey typically use a coating made of MgFl2, which has an index of 1.38. The ideal glass for that coating would have an index of 1.9, which is not av ailable. So the higher the index of the glass, the better the ARC, when you are using MgFl 2 as a coating. Problem 2: Wavelength dependency. The path condition can only be exactly met for one ... WebRefractive indices describe the ratio between the speed of light in a vacuum and the speed of light in another medium. Most transparent media have a refractive index of between 1.0 and 2.0. Whilst the refractive index of a vacuum has the value of 1.0, the refractive index of water is 1.333. The ratio between them is therefore 1:1.333. electricity baseload
