WebRefractive Index (Index of Refraction) is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density. The refractive index variable is most commonly symbolized by the letter n or n' in descriptive text and mathematical equations. Figure 1 - Refraction of Light WebThe index of refraction is often described as an apparent decrease in the speed of light from to as it passes through a dielectric medium. In fact, light photons do not actually slow down, but the effect is simulated by a retarding phase shift in the emerging electromagnetic waves.

Web5. okt 2012 · The refractive index of a solid is defined as the ratio of the speed of light of a specific wavelength in a vacuum to its speed in the solid. The change of the refractive index with wavelength is called the dispersion. In a solid, the refractive index may also be dependent on the direction the light takes through the material.
