Light enters a 10 cm thick, parallel face, glass block at normal line drawn through the block. The angle of incidence for the light is 30 degrees. Light leaves the block, moved a distance, 3 cm, along the exit face as measured from the point of exit to the normal line. What is the index of refraction of the prism?
