This relationship predicts the existence of creep waves, which are less useful than Rayleigh waves for nondestructive testing.
This relationship predicts the existence of creep waves, which are less useful than Rayleigh waves for nondestructive testing. The boundary conditions of Maxwell's equations, along with Fermat's principle of least time, may be used to derive it, and a quantity named for Brewster can be calculated from this law assuming complete reflection. Involved in the derivation of the critical angle, this relationship predicts an angle of fifty degrees will produce total internal reflection at a water-air boundary. For 10 points, identify this relationship which determines how the angle at which light enters and exits a boundary changes due change in refractive index.
