Question

relation between dielectric constant and refractive index

Answer 1

The refractive index of a material, n, is defined as the ratio of the speed of light in a vacuum to the speed of light in that material. ... It is possible to derive another equation for the speed of light, this time in terms of the electric permittivity (ε) and magnetic permeability (μ) of the material

Answer 2

Answer:

low of refraction ( Snell"s law)
