(adsbygoogle = window.adsbygoogle || []).push({}); 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.
