WebIn simple words to understand, refractive index is the relative speed of light in a medium compared to the speed in vacuum. Thus if a medium have a refractive index of 1.5, the light will travel through that medium with a speed of 1/1.5 i.e. 0.67 times the speed of light in vacuum. The speed of light in vacuum is 300,000 km/second. WebMay 15, 2024 · Refractive index profile calculation.
