Enter the speed of light and the speed of light in a medium, and this calculator will determine the index of refraction. The index fraction is calculated with the formula presented below. This formula is also known as snell’s formula.

## Index of Refraction Formula

The formula for calculating a refraction index is as follows:

n = c / v

- Where n is the index of refraction
- c is the speed of light in a vaccum = 299,792.46km/s
- v is the speed of light in a given medium
