This value, the square root of the product of the relative permeability and relative permittivity, is negative in metamaterials, and multiple values for it appear in objects exhibiting birefringence. The angles of incidence for two adjacent objects with different values of this are calculated by Snell's law. For 10 points, name this dimensionless quantity measuring the ratio of the speed of light in a medium to that in a vacuum.
