According to Snell’s law, the angle of refraction θ₂ of a light ray traveling in a medium of index of refraction n is related to the angle of incidence θ₁ of a ray traveling in a vacuum through the equation sin θ₁ = n sin θ₂. Assume that θ₁ = 0.3672 ± 0.005 radians and θ₂ = 0.2943 ± 0.004 radians. Estimate n, and find the uncertainty in the estimate.
