Refractive Index Calculator

Posted by Dinesh on

Calculate index of refraction using refractive index calculator online. In optics, the refractive index or index of refraction n of a material is a dimensionless number that describes how light propagates through that medium.

Refractive Index Calculation

Formula:

n = c / v

where,
c - the speed of light in vacuum
v - the phase velocity of light in the medium.
n - refractive index
