In the figure, a light ray enters a glass slab at point A at incident angle 01 = 67.50 and then undergoes total internal reflection at point B. What minimum value for the index of refraction of the glass can be inferred from this information? Assume that the index of refraction of air under standard temperature (0 C) and pressure (1 atm) is 1.00029. Incident e1 ray Air A Glass B Number i 1.254209517697 Units This answer has no units v
