1. The problem statement, all variables and given/known data Sunlight strikes a piece of crown glass at an angle of incidence of 36.7 degrees. Calculate the difference in the angle of refraction between a orange (610. nm) and a violet (410. nm) ray within the glass. The indices of refraction for the orange and the violet are n = 1.522 and n = 1.538, respectively 2. Relevant equations I know that the angle of incidence = the angle of reflection 3. The attempt at a solution I don't really know how to solve this with the information I'm given. I have no idea where to start. Can someone help me?
