Do Light Have Refractive Index?

The refractive index of materials varies with the wavelength (and frequency) of light. This is called dispersion and causes prisms and rainbows to divide white light into its constituent spectral colors. ... For visible light normal dispersion means that the refractive index is higher for blue light than for red.

What is the refractive index of light in?

Refractive 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.

Which light has highest refractive index?

The refractive index is maximum for violet colour.
