The drawing shows a ray of light traveling from point A to point B, in a material that has an index of refraction n1 = 2.28. At point B, the light encounters a different substance whose index of refraction is n2 = 1.64. The light strikes the interface at the critical angle of θc. What is the critical angle θc?
