Light changing direction when passing between materials
n=sinisinrn = \frac{\sin i}{\sin r}n=sinrsini
Refractive index of the material
Angle of incidence (measured from normal)
Angle of refraction (measured from normal)
Line perpendicular to surface at point light enters
Constant for a material; equals refractive index
Refractive index of the glass block
Through the origin
Always greater than 1
Error when reading angles on protractor
Improves accuracy and reduces percentage errors
