This quantity is related to a specific wavelength, lambda, by A lambda squared plus B plus C lambda to the minus two plus D lambda to the minus four, where A through D are material constants, in Cauchy's equation.
This quantity is related to a specific wavelength, lambda, by A lambda squared plus B plus C lambda to the minus two plus D lambda to the minus four, where A through D are material constants, in Cauchy's equation. It is sometimes useful to derive this quantity as the square root of relative permittivity times relative permeability. The arcsine of the ratio of this quantity for two media gives the critical angle for (*) total internal reflection. The ratio of this quantity for two media is equal to the ratio of the sine of the angle of incidence and sine of the angle of transmittance according to Snell's law. For 10 points, name this quantity symbolized n and equal to the ratio of the speed of light in a vacuum to the speed of light in a material.
