Unformatted text preview: , _ 2 4 4. If light travels from air into sylvite, and the angle of incidence is 29.6°, what is Ê r? n for sylvite = 1.490. Brewster’s Law of maximum polarization is: 4 5. For sylvite, what is Ê i? The critical angle is given by a variation of Snell’s Law: 4 6. Suppose light passes from sylvite into air. What is the critical angle? HINT: Remember that light is going from sylvite into air. What is the incident medium? The formula for the Numerical Aperture (N.A.) Is: 4 7. If the angular aperture is 35.7°, and n = 1.544, what is N.A.?...
