Optic refraction
WebRefraction occurs when light travels through an area of space that has a changing index of refraction; this principle allows for lenses and the focusing of light. The simplest case of refraction occurs when there is an … WebA key property of the optical system is its level of dispersion, but this depends on both the properties of the grating and how it is used. A grating itself cannot be given a specification detailing how a certain amount of rotation corresponds with a certain separation of wavelengths without knowing other system details.

Transcribed image text: Consider a fiber optic cable: the core has a refractive index ncore, and the cladding has a refractive index ncladding. . Make a diagram that illustrates the situation, and answer the following questions: - How can you use total internal reflection to guide light rays inside the fiber?
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.
