WebAnswer (1 of 18): The refractive index(RI) cannot be compared without first knowing the frequency of the incoming radiation. It is decided based on the ratio of speed of light in both media, the medium's permittivity and the final direction of propagation. Under natural conditions, the record h... Web18 de ago. de 2024 · One of the highest refractory index in liquids is 1.79 ( 20 ∘ C) possessed by a solution of sulfur in methylene iodide ( C H X 2 I X 2). Liquids are less dense than solids and this explains why it's difficult to have a refractory index greater than 2. According to Anderson and Payne [ 1 ]:

Many materials have a well-characterized refractive index, but these indexes often depend strongly upon the frequency of light, causing optical dispersion. Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength (λ) of 589 nanometers.

Plastic materials (such as nylon, polycarbonate,…) can be found within the 1.5 – 1.71 range of indices, whereas glass reaches 1.9.
The refractive index is an important property of the components of any optical instrument. It determines the focusing power of lenses, the dispersive power of prisms, the reflectivity of lens coatings, and the light-guiding nature of optical fiber. Since the refractive index is a fundamental physical property of a substance, it is often used to identify a particular substance, confirm its purity, or measure its concentration. The refractive index is used to measure solids, liquids, and …
