Find the critical angle for light passing from air to glass if the angle of incidence is 75°. Group of answer choices: A. 40.1° B. No critical angle. C. 75° D. 90° 2. Consider light passing from higher to lower refractive mediums, calculate the transmitted angle (in degrees) if the critical angle is 71°. Round to 2 decimal places. 3. Suppose n1 = 1.7 and n2 = 0.63, if the transmitted angle is given as 31°, what is the angle of incidence in degrees? Give the answer to 2 decimal places.
