Short Wavelength light
The longer the wavelength, the greater the angle of refraction.
how can the path of a light ray be affected once it enters a nonzero angle with a greater index of refraction
17° to the normal.
A medium with a higher index of refraction, like diamond, is more dense than the medium with a lower index of refraction, like air. If the ray of light is moving from the less dense medium (lower index of refraction), to a more dense (higher index of refraction) the ray of light bends TOWARDS the normal.

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.
Light refraction through a diamond is by design -- the design of the cut.
The longer the wavelength, the greater the angle of refraction.
Clarity of a diamond is an ANSII standardized procedure that involves placing a light near the diamond and measuring the refraction.
Colorless. Any color it appears to have is due to the refraction of light.

Diamond, because its facets have more surfaces from which to bounce light than does a pane of glass.
17° to the normal.
A medium with a higher index of refraction, like diamond, is more dense than the medium with a lower index of refraction, like air. If the ray of light is moving from the less dense medium (lower index of refraction), to a more dense (higher index of refraction) the ray of light bends TOWARDS the normal.
This means no refraction occurs i.e. Total internal reflection (all light reflected) occurs
When the angle of incidence is greater than the critical angle,the light ray reflects into denser medium at interface. This is total internal refraction
It is because the index is related to the velocity of light in air (ideally vacuum) and the medium in question. Since the velocity of light in vacuum is greater than it can be in any other media, the index of refraction of these other media relative to the vacuum is greater than 1.However, if you studied light travelling through glass and then water, the index of refraction between those two would be 0.89 (approx).
