Index Of Refraction

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.
