Question

A prism with angles 45 , 45,and 90 is to be used to turn a beam of lightthrough a 90 angle. What is the minimum index of refraction for the material ofthe prism that will give the total internal reflectionneeded? Any help is greatly appreciated, will grade fast.Thanks!

Explanation / Answer

The equation that relates indexes with the angles is: The index for air (n0) is 1, so the equation simplybecomes (with both and = 90o): nprism = 1.4142
