Define the terms isotropic and anisotropic medium.

An isotropic medium is a medium in which all the properties are uniform and is independent of direction. These have same and consistent chemical bonding. These are used for windows and glasses. These have single refractive index. Anisotropic medium refers to the medium in which the properties are different in all the directions. These have different and inconsistent chemical bonding. These are used for polarisers, wedges. These have many refractive indexes.
