What happens if the angle of incidence (from inside the material) is greater than the critical angle of refraction found in part (a) above? Why? This is called total internal reflection.

  1. Why is it only possible to have total internal reflection when light travels from a medium of higher index of refraction to one of lower index of refraction?
