n=1.331 for red light in water and n=1.34 for blue light in water. If a ray of white light enters the water at 83 degrees what are the underwater angles of refraction for the blue and red components of white light?

Also using Snell's law :

(sin theda 1/ sin theda 2) = (n2/n1)

so that theda 1 =83 degrees. What would be n2 and n1? Is n2 for the blue or red n also what would n1 be?
