Relative permittivity refractive index

WebMany textbooks and online sources give the relative permittivity of water as about 80 and the refractive index as 1.33. If you use the definition of refractive index to find the speed of light in water, you will find v = c/n ~ 2.56e8 m/s. However, if you use the equation to find the speed of light in a medium, c = 1/sqrt (permittivity ... WebFor cubic materials, the index of refraction is the same along the two transverse directions. However, for anisotropic media, the indices of refraction may be different for the two …
