Light in air is initially traveling parallel to the face AC of an equilateral triangular prism, as shown in the figure.
 
  The prism is made of glass with an index of refraction of 1.52. If the light does not strike the face AC, what is the angle between the ray as it leaves the prism at face BC and the normal in air at that face?
 
  A) 83
  B) 19
  C) 59
  D) 27
  E) 55

Question 2

A ray of light passes from glass into a liquid, as shown in the figure. What is the speed of the light in the liquid? (c = 3.00  108 m/s)
 
  What will be an ideal response?
