Index of Refraction
The index of refraction is a description of
the speed of light in a material.
c is the speed of light in vacuum.
v is the speed of light in a material.
n is the index of refraction for that material.
n = c/v
Typical values for the index of refraction:
n(ice) = 1.30
n(H2O) = 1.33
