Light does not refract via a single material. Refraction occurs when light passes from one material into another of a different density. It is the amount of difference in densities that causes the refraction. The greater the difference the greater the refraction.
I believe that the densest material would be diamond, so light passing through a diamond and into a vacuum would seem to be the greatest difference, causing the greatest refraction.
Its optical density.
No, the amount a lens refracts light depends on its material and curvature. A less curved lens will refract light less than a more curved lens if they are made of the same material. The refractive index of the material and the curvature of the lens both play a role in determining the amount of refraction.
Violet because it has a shorter wavelength and higher frequency
A prism. It can be made of glass, crystal, or other hard clear material.
The refractive index of the material the prism is made of determines how much a particular color refracts as it passes through the prism. Different colors of light have different wavelengths, which causes them to refract at slightly different angles due to the material's refractive index.
The refractive index of the material the prism is made of is the main factor that determines how much a particular color refracts as it passes through a prism. Different colors of light have different wavelengths, which interact differently with the material's refractive index, causing them to bend by different amounts.
white light
The cornea is the main structure that refracts most of the light entering the eye. It is the clear outer layer that covers the front of the eye and helps to focus light onto the retina at the back of the eye.
Violet light refracts the most from a prism because it has a shorter wavelength compared to other colors, causing it to bend more when passing through the prism.
Blue refracts the most in a prsm than yellow
-- Its speed increases. -- Its wavelength increases. -- It refracts away from the normal to the interface at the point of incidence.
Refraction is caused when light changes the medium that it is moving through. Therefore any material that is transparent to light will diffract it.
