1. The problem statement, all variables and given/known data a)What is the minimum refractive index of the prism in order for the light to reflect? b) What is wrong with this ray path for a reflecting prism? 2. Relevant equations nisin(theta 1)= ntsin(theta 2) 3. The attempt at a solution for part a, nt is 1, theta 2 is 90 degree, theta 1 is 50 degree, then i got ni = 1.3 For part b, i have no idea about it..
