What color of light has the highest refractive index?
The refractive index is inversely proportional to the wavelength, so the shorter the wavelength (the higher the frequency, or the more "blue" the light) the higher the refractive index. Conversely, the longer the wavelength (the lower the frequency, or the more "red" the light), the lower the refractive index. Therefore as wavelength of blue in less the refractive index will be maximum. For more information, follow the related link below.
What is speed of light in more refractive index?
Higher the refractive index, less the speed of light
What can you tell us about the refractive index?
"The refractive index is a measure of how much light bends or refracts when it is passed through a certain medium. The higher the numerical value of the refractive index, the more that light suffers from refraction."
What is meant by the refractive index of a diamond is 2.42?
The number is comparative. Refractive index is a dimensionless number that represents how fast radiation -- in this case, light -- travels through a medium, in this case, diamond. The number assigned to a diamond is the highest number on the scale. The scale includes gases, liquids and solids. This means that with a refractive index of 2.42, 'light travels 2.42 times as fast in vacuum as it does in a diamond'. You can read more about refractive indices, below.
What number indicates how optically dense a substance is?
I predict you are talking about the refractive index. the higher the value, the more dense the substance and thus light undergoes greater refraction (bending of light as it passes thru different mediums) the refractive index = sin of the angle of light made with normal in the less dense medium divide by the sin of angle in the denser medium.

What colour is refracted most when passing triangular prism?
violet is most refracted when passing through a triangular prism because refractive index of violet is more and dispersion is directly proportional to ref index
What refracts more red or violet?
Light doesn't have a refractive index. The medium or substance through which the light travels has the refractive index.
What does the term density and refractive index mean?
The optical density of a medium is not the same as its physical density. The physical density of a material refers to the mass/volume ratio. Optical density determines how much a light wave is slowed down as it passes through a medium. The more optically dense a material is, the slower that a wave will move through the material.The refractive index is a measurement of optical density. A medium with a low optical density, would have also a low refractive index.For example air, having a low optical density has a refractive index of 1.0003, whereas water, with a higher optical density, has a higher refractive index of 1.333.
Why does diamond shine more than emerald or ruby?
'Shine' is an observed, subjective judgement, and you are the judge. At least two characteristics are involved in gemstone shine: cut/ clarity of the stone and the innate refractive index of each. A flawless diamond of an excellent cut is impossible to match in terms of gemstone shine. Both emeralds and rubies are valued on colour, then on clarity or cut. Practically, diamond has a high refractive index 2.4 according to "Standard refractive index measurements taken at yellow doublet sodium D line, with a wavelength of 589 nanometres"1. Ruby measures 1.76 and emerald measures 1.57. You can compare gemstones and the refractive index of each, below. ________________ 1 Wikipedia: List of Refractive Indices
Why the refractive index of ice is lower than that of water?
The refractive index of a certain material increases with its density. The refractive index of ice is less because it has a lower density than liquid water.

Does Light Travel More slowly in a Medium?
Light travels at its maximum velocity c in a vacuum. In a medium with a certain refractive index, it is slowed down and travels with velocity c/index
Can light moves more slowly than air in the water?
Light in water is 1.333 times slower than light in the air. The reason is that the light is transformed into potential energy in the electrons and exits again as a light particle, so in air it performs the transformation less than in water. Air has a refractive index which is close to a vacuum, refractive index 1.000, whereas in water the refractive index is 1.333. The index is used when calculating the many different effects substances have on light. The index itself changes, depending on the wave length (ultraviolet, infrared, etc.)
Advantage of graded index fiber over step index fiber?
A graded index multimode fiber will transmit 800 modes, and has a varying refractive index. A step index multimode will transmit 228 modes.
