A thin beam of light enters a thick plastic sheet from air at an angle of 32.0 with the normal and continues in the sheet at an angle of 23.0 with the normal. What is the index of refraction of the plastic?
 
  A) 0.74
  B) 1.11
  C) 1.28
  D) 1.36

Question 2

The index of refraction for a certain material is 1.399 for red light and 1.432 for blue light. Light containing both of these colors is traveling in vacuum and strikes a flat sheet of this material.
 
  Find the angle separating the two colors in the refracted light in the sheet if the angle of incidence is 60.00.
