1. Draw a sketch of the physical situation with all given physical quantities clearly labeled. Show the path the laser follows until it reaches surface B in your sketch (do not make any assumptions about what will happen to the path of the laser after it reaches surface B in this sketch). 2. Determine the angle (from the normal) with which the laser hits surface B. Clearly show all steps, starting from generalized equations. Explain your mathematical work in words. Your explanation should cover both what you did and the thought process behind why you did that. 3. Draw a ray diagram which represents the path the light takes after it is incident on surface B. Include any reflected and refracted rays that exist in your ray diagram. Determine the angle(s) of this/(these) ray(s) with respect to the normal at surface B. Explain any mathematical work needed to complete the ray diagram in words. Your explanation should cover both what you did and the thought process behind why you did that. (you do not need to follow through with any subsequent reflections or refractions that may or may not occur after surface B) 4. Evaluate your answers. Consider all aspects of your answer (the numerical value, sign, units, behavior, etc) in your evaluation.
