What is diff between relative refractive index and absolute refractive

1.	What is diff between relative refractive index and absolute refractive index
Answer» RELATIVE REFRACTIVE INDEX :-relative refractive index is defined as a ratio of speed of light in vaccume and in selective medium.ABSOLUTE REFRACTIVE INDEX :-the absolute refractive index is defined as a speed of light in two different media. uffs, sory yar,Actually galti se mistake ho gyi.? I asked it for chemistry not physics Are pande ji ye to potential difference bata rhe ho the relative refractive index is the distance between infinity to at a fix point.and absolute refractive index is the the distance between two fix point where the voltage is pass. I also want to ask this question
