In addition, the new cell design permits the measurement of the refractive index, RI, of a fluid relative to the refractive index of the material comprising or surrounding the flow cell. Thus a single instrument may be used to measure separately the RI of a sample fluid and the DRI between...
125K When a light wave passes from one medium into another, it changes direction in a process called refraction. This lesson investigates the properties of refraction, including the index of refraction and the ratio known as Snell's Law. Related to this QuestionWhat...

Forum:Special and General Relativity Calculating Critical Angle: Relative vs. Absolute Refractive Index Greetings, Do we use Absloute refractive index when finding crtical angle ? if it was two mediums ( not vacuum or air) how would i calculate the critical angle ? I mean i get confused when...

[epsilon].sup.*], respectively, [epsilon] is the relative permittivity, [kappa] is the effective conductivity, [[epsilon].sub.0] = 8.8542 x [10.sup.-12] F/m is the absolute permittivity of vacuum, and [omega] = 2[pi]f (where f is the frequency) is the angular frequency of the...
That is, perhaps Newton and Leibniz agreed on the physically objective status of simultaneity and instantaneous Euclidean geometry--enough structure to define relative motion--but absolute space adds something to that structure that allows us to describe absolute motion, and one could claim that adding...
