Problem
A ray of light confined within sapphire (n=1.77) strikes its flat boundary with water (n=1.33) at an angle of 50∘ to the normal. Determine whether the ray will refract into the water or undergo total internal reflection, and support your conclusion with an appropriate quantitative comparison.
