Question
This equation is only valid for non-magnetic materials without a permanent dipole moment. For 10 points each:
[10m] Name this equation that sets the quantity n squared minus one over quantity n squared plus two equal to four thirds pi times particle number times alpha. It relates the index of refraction to the mean polarizability and density of a material.
ANSWER: Lorentz-Lorenz equation
[10e] The Lorentz-Lorenz equation can be derived from the Clausius-Mossotti relation as the refractive index equals the square root of the relative form of this quantity, denoted epsilon sub r, which is contrasted permeability.
ANSWER: relative permittivity [accept dielectric constant]
[10h] This scientist developed an analogue of the Clausius-Mossotti relation for polar substances that shows linear behavior in the high-temperature regime. This scientist names the classical limit of the Brillouin function, which gives the magnetization of a paramagnet.
