1. The problem statement, all variables and given/known data A ray of light strikes the midpoint of one face of an equiangular (60◦, 60◦, 60◦) glass prism (n = 1.3) at an angle of incidence of 33◦. a.Trace the path of the light ray through the glass, and find the angle of refraction at the first surface. b.Find the angle of incidence at the second surface. Answer in units of ◦ c.Find the angle of refraction at the second surface. Answer in units of ◦. 2. Relevant equations n1sin(theta1) = n2sin(theta2) 3. The attempt at a solution So I have part a correct which is 24.7685 degrees. I used the equation to solve for theta2. However I cannot get b because my reasoning is that the angle of refraction in part a is the angle of incidence in part b and this is obviously not right. I do not know where to go from here.
