What is the index of refraction for light traveling through different media?
The following are some sample indices of refraction. The index of refraction, represented by n, is the ratio of the speed of light in a vacuum divided by the speed of light in the material. The larger the index of refraction, the greater the bending that takes place.
|Medium||Index of Refraction (n)|
|Air (usually rounded to 1.0)||1.003|
