Homework Help: Simple Law of Refraction Problem

  1. Jan 15, 2008 #1
    1. The problem statement, all variables and given/known data
    I am studying the Law of Refraction. I am at a point in my textbook called a "checkpoint". These are supposed to be simple questions to test understanding. I'm apparently not understanding thus far because I cannot figure out this problem.

    2. Relevant equations
    Snell's Law?

    3. The attempt at a solution
    I'm sure the angles of line segments b and c (relative to a?) will be the determining factor. Since the problem says "original materials a" does that mean we measure all angles relative to line segment a? How do I proceed more mathematically on this problem - perhaps using Snell's law?

    Definitely use Snell's law. Measure angles with respect to the normal, as usual with Snell's law.
