Refractive index is the ratio of speed in a vacumme as to speed of light in a medium. The slowest speed of light is attain by use extremely cold sodium atom as light medium and it is succeed to slow down the speed of light from 186,000 Mile/second to 38 Mile/hr (300,000,000 m/s -> 17 m/s).
This account to refractive index of 17,621,000
The index of refraction of a substance describes the speed of light in that substance,
as a ratio of the speed of light in vacuum to its speed in that substance.
Index Of Refraction
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.
The ray of light bends towards the normal.
n(index of refraction) = c(speed of light in a vacuum)/v(speed of material in the sebstance)
The substance's index of refraction isSpeed of light in vacuum / Speed of light in the substance

Q: How do you think increasing a medium's index of refraction might affect the angle of refraction?
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.
Each substance has an index of refraction. The index of refraction of water is about 1.3330 . The index of refraction of air at standard conditions is about 1.0003 . There is no such thing as the index of refraction of "water to air".
Use the definition of "index of refraction". In this case, you simply need to divide the speed of light in a vacuum by the index of refraction.

well kids, the answer is INDEX OF REFRACTION. (: science question on my homework
c divided by the index of refraction of the medium = the speed of light in the medium.
Water's index of refraction is 1.333
The speed of light stays constant
