Homework Help: What is deviation(optics)?

  1. Feb 20, 2012 #1
    1. The problem statement, all variables and given/known data
    I don't quite understand what deviation or the deviation angle is.

    2. Relevant equations

    3. The attempt at a solution
    I have no idea what it is. Is it the angle that it enters the prism - the angle that it leaves the prism.
