how to find speed of light given refractive index. The amount by which light slows in a given material is described by the index of refraction n. N fraccv where n refractive index of the medium c speed of light when in vacuum v speed of light when in medium.
Refractive Index Definition Equation Britannica from www.britannica.com
In a glass with refractive index the speed of light will be in m s. Speed of Light in the 1st medium - v₁. The refractive index formula is given as follows.
N 1 is the refractive index of the first medium from which the ray travels n 2 is the refractive index of the second medium to which the ray travels This is known as Snells law.
Calculate the refractive index of the material of a glass slab. Take ice for example which Im working with here whose refractive index varies as a function of depth. Where i is the angle of incidence and r is the angle of refraction. The refractive index formula is given as follows.
