Refractive Index Calculator

Calculate Refractive Index

Use this simple physics Calculator to calculate refractive index (index of refraction) of a material that describes how light propagates through that medium.

refractive indices at ?=589 nm
Materialn
Vacuum1
Gases at 0

Formula:

n = c / v

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