Now that is an interesting remake of the Newton Experiment of 1671. In it the idea that refraction is to physics what the dy/dx is to Calculus and that no curves can exist in either physics or mathematics.
Snell's law is another way of saying dy1/dx1 is proportional to dy2/dx2.
Snell's law comes from the Maxwell Equations and thus, we prove that Physics has no curved lines but whenever we think we have a curved line like a gravity trajectory, what we really have is a collection of tiny straightline segments that appear to be a overall curve.
