WebThe refractive index between two materials is: 1 n 2 . It is the ratio of speed of light in material 1, to the speed of light in material 2, and is given by: 1 n 2 = c 1 /c 2 = n 1 /n 2. …
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 sometimes μ . The refractive index, n, of a material is defined as. n = c v. where c is the speed of light in a vacuum and v the speed of light in the material.
