When light passes from one substance to another, and both have the same refractive index, then there will be no refraction - or change of direction - at the border. It is as if there were only one substance.
Lead monoxide is used to increase the refractive index of glass.
The (very high) refractive index of diamond is 2.4 at room temperature.(From Wikipedia: "Refractive index also describes the quantity that light is bent as it passes through a single substance."
The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium.A simple, mathematical description of refractive index is as follows:n = velocity of light in a vacuum / velocity of light in mediumHence, the refractive index of water is 1.33, meaning that light travels 1.33 times as fast in a vacuum as it does in water.
Yes refractive index of the material of the medium [glass] with respect to air is high for violet and low for red.

Refractive index is a physicsâ?? measurement used to figure out the bend length a ray of light takes when passing through objects.
It depends upon the material of the substance

No. The refractive index is an absolute measure that determines by how much the angle of incidence is different from the angle of reflection.

Part 1 - WHY does refractive index vary?The refractive index of a material is determined by how quickly light travels through it. Different wavelengths travel at different speeds, hence the refractive index varies with wavelength. This is known as (chromatic) dispersion.In glass, red light travels faster than blue light, which is why a prism can be used to split white light into a rainbow.Part 2 - HOW does refractive index vary? (ie. Define the relationship).Sorry - I haven't a clue. I'm looking for the answer as well!
Light doesn't have a refractive index. The medium or substance through which the light travels has the refractive index.
The refractive index of any substance is(speed of light in vacuum)/(speed of light in that substance) .The number is greater than ' 1 ' in any material medium.
