What I wanted to make clear is that the refractive index is the only material property you need to know to calculate optical response (i.e. apparent color), at least in the realm on linear optics. $\endgroup$ – Web19. jan 2024 · The refractive index of a material is a property of its electronic structure. If addition of charge changes the electronic structure, then the refractive index changes. Optics is the branch of physics related to the interaction of light and matter. This interaction can be observed on a daily basis in a number of different scenarios.
WebRefractive index is a material property that describes how the material affects the speed of light travelling through it. Refractive index is usually represented by the symbol n, or … WebThe methods and set-ups used for measuring the refractive indices of bulk materials are based on the index-induced phenomena described in Sect. 29.2.3, mainly angular deviation of light by refraction through prisms, and also, to a lesser degree, total internal reflection including critical angle, and in some cases Brewster angle measurements.
