Want this question answered?
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.
Index Of Refraction
The substance's index of refraction isSpeed of light in vacuum / Speed of light in the substance
The index of refraction of a substance is(The speed of light in vacuum) divided by (the speed of light in the substance) .
The ray of light bends towards the normal.

Index Of Refraction
c divided by the index of refraction of the medium = the speed of light in the medium.
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.

The refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium.
When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of..........=refraction

Speed of light in air (which has an index of refraction of 1) is 3 * 10^8 m/s. So divide the speed of light by the index of refraction of the new medium to obtain the speed of light in that medium. Hope I helped!!
Water's index of refraction is 1.333
