Why does a prism cause white light to separate into the spectrum?
Because different colours have different have speeds in a prism , as refractive index depends on speed of the object therefore different colours have different refractive indexes
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.
Why does refractive index not have units?
Because it is the ratio of two speeds (which will have identical units), the units cancel.
Is refractive index a chemical property?
The only reason a material is able to reflect light is because of its smooth surface and the substance that it is made of which are physical property
Why is chromatic aberration more evident for some positions of the aperture?
The further the aperture is from the optical axis of the lens, the more to the side of the lens the incident light falls. The further the light falls from the optical axis, the greater the effects of chromatic aberration. This is because different wavelengths of light have different refractive indices (dispersion). Because of Snell's Law, n1sintheta1=n2sintheta2, the greater the angle of incidence, the more pronounced the effects of the difference in refractive indices. Spherical aberration further enhances the chromatic dispersion.

What island is north Atlantic is splitting apart?
the island is splitting apart because it is following the rule of pangea
Why do you use the words does do are and is in sentences at different times?
Because it describes what you are saying or doing
How do you xxplain the cause of dispersion?
When composite white light with seven colours as constituents enter into triangular prism, then different colours get refracted at different angles because of the different refractive index value of glass for different colours. Refractive index is defined as the ratio of the speed of light in free space to that in the glass medium. As the speed of the different colour differ, the refractive index varies. Hence they have different angle of refraction. So all the colours have been split up. As we use a triangular prism, as the refracted colours fall on the other face of the prism, once again separation becomes possible. Hence the phenomenon of dispersion. But this will not be possible when we use a rectangular glass slab. So triangular prism is essential to have dispersion.
Explain why cut diamonds have billiance and why they have fire?
Because they are polished and have a high refractive index
Why Glycerin is not visible when kept in Glass bottle?
Because it has the same refractive index as glass.
How did they get Civil War?
They got it because takethat were splitting up

Are results different between IOL surgery and Lasik surgery?
These are two very different types of technologies and procedures and usually for different indication. IOL surgery stands for intraocular lens surgery and is replacing the natural crystalline lens with a plastic lens. This is usually done for patients with cataracts who cannot see without having their lens removed. More recently, some patients are undergoing what is termed a refractive lens exchange. This means taking out a clear lens and putting in a plastic one for the purpose of correcting refractive error and thus enters the realm of refractive surgery. Refractive surgery, the operation(s) for correcting vision to reduce or eliminate the need for glasses or contacts includes LASIK which is a laser procedure done under a protective flap. This is the most frequently performed refractive procedure accounting for perhaps 85% or more of all refractive procedures. Next in frequency is PRK or a surface laser procedure, and refractive lens exchange is only done on less than 5% of all refractive procedures. Of course when someone needs cataract surgery there is a refractive component because these patients want to be able to see well without glasses, but this is different from a primary refractive procedure.Refractive lensectomy or refractive lens exchange is typically done on older patients who have or will be getting cataracts shortly, that is typically over the age of 55 or 60 years. Also this can be done for types of corrections that do not do as well with LASIK such as high degrees of corrections, especially farsightedness.Ultimately, on the same patient one would expect similar results for IOL surgery and LASIK if both were in the range to expect a good result. The technology for both are extremely good and both can result in satisfied patients. The risk profiles are different between the procedures, since the IOL is intraocular, that is within the eye, it comes with some more serious risks for complications.

What is the index of refraction of sugar?
Crystaline sugar (sucrose) has a refractive index of around 1.56. Sugar solutions can have refractive indices greater than this. Note, that the refractive index of a substance can even be determined for opaque substances. This is because the RI also determines reflective properties. So by measuring the amount of light reflected by light shining on a polished sample at a given angle, a refractive index can in principle be obtained.
