1.) Sunlight strikes a piece of crown glass at an angle of incidence of 37.4o. Calculate the difference in the angle of refraction between a orange (610 nm) and a blue (470 nm) ray within the glass. The index of refraction is n=1.522 for orange and n=1.531 for blue light.
2.) The ray now travels inside the glass. What is the minimum angle of incidence at which the orange ray can hit the surface of the glass and become there totally internally reflected and not refracted?
