According to Snell’s law, the angle of refraction 
of a light ray traveling in a medium of index of refraction n is related to the angle of incidence 
of a ray traveling in a vacuum through the equation sin = n sin. Assume that ?1 = 0.3672 ± 0.005 radians and = 0.2943 ± 0.004 radians. Estimate n, and find the uncertainty in the estimate.
