1. The problem statement, all variables and given/known data A red beam of light in air enters crown glass at an angle of 60.00 to the normal. Find the angleof refraction. Repeat for a violet beam oflight entering crown glass (same angle). 2. Relevant equations Not too sure, I believe I would use Snells law here.. does that sound correct? 3. The attempt at a solution do not have an attempt because I do not know which equations to use.
