Refractive index water

Many materials have a well-characterized refractive index, but these indices depend strongly. International Association for the Properties of Water and Steam . In optics, the refractive index or index of refraction n of a material is a dimensionless number. For example, the refractive index of water is 1. Optical constants (refractive index and extinction coefficient, n k) of H O, D O (Water, heavy water, ice): Hale and Querry 1973: Water; n,k 0. Some common fluids and their refractive indexes. The approximate speed of light in water can be calculated as. Most people would assume that the refractive index of water is known to a high degree of accuracy.

For some materials such as water, light will slow down more than electrons will. The index of refraction of a material is defined by the speed of light in vacuum . Alliance, Millennium, and Waters are registered trademarks of Waters. Intended use of the Waters 24Refractive Index Detector.

The IAPWS has published the absolute refractive index of water, that is relative to a vacuum. We have calculated its refractive index, relative to air, by dividing .
