Refractive index notation

WebJul 16, 2012 · The refractive index requires a bit of explanation. It represents (in a very specific sense) the fraction by which the speed of light is decreased in that particular medium. In other words, the speed of light in vacuum is meters/second, and the speed of light in the medium is . WebMar 24, 2024 · The word "index" has a very large number of completely different meanings in mathematics. Most commonly, it is used in the context of an index set, where it means a quantity which can take on a set of values and is used to designate one out of a number of possible values associated with this value.
