The Sellmeier equation expresses the interaction between wavelength and this quantity, two values of which exist for objects that exhibit (*) birefringence.
The Maxwell Relation defines this quantity as the square root of the dielectric constant. "Left-handed" objects possess a negative value for this quantity and are called metamaterials. The Sellmeier equation expresses the interaction between wavelength and this quantity, two values of which exist for objects that exhibit (*) birefringence. This quantity's ratio for two objects is identical to the ratio of the sines of the incidental angles according to Snell's Law. For 10 points, give this name for the ratio between the speed of light in a given medium and the speed of light in a vacuum.
The Maxwell Relation defines this quantity as the square root of the dielectric constant. "
