WebJul 16, 2012 · In short, refraction is the bending of a ray of light when it passes from one medium to another. Unlike optical phenomena like diffraction and interference, which usually require careful experimental preparation to be observable, refraction is readily seen all … WebFinally, n2 = ε/ε0 so we can express the index of refraction as a function of the angular frequency of the light as: n2(σ) = 1 + This is known as the dispersion equation. For frequencies above resonance (σ02 - σ2) < 0, the oscillators are about 180 o with the driving electric field (see the discussion of phase-lag) , and n < 1.
