The amount of refraction in a material can be determined using the index of refraction.
The index of refraction can be used to calculate the speed of light in that material.
The greater the index of refraction, the more the speed of light will slow down in that material.
MEASURING REFRACTION
ratio of the speed of light in a vacuum to the speed of light in a medium
speed of light in air almost as fast as vacuum so it is 1.00 the higher the value, the more it will slow down
n = index of refraction
c = speed of light in a vacuum = 3.0 x 108 m/s
v = speed of light in a substance (m/s)
index of refraction also found by measuring the angles of incidence and refraction and calculating sin n = sin ∠i
