A ray of sunlight is passing from diamond into crown glass; the
angle of incidence is 28.00°. The indices of refraction for the
blue and red components of the ray are: blue
(ndiamond = 2.444, ncrown
glass = 1.531), and red (ndiamond =
2.410, ncrown glass = 1.520). Determine the
angle between the refracted blue and red rays in the crown
glass.

do | = | ---Select--- cm cm^-1 no units |
(b) What is the focal length of the lens?
f | = | ---Select--- cm no units cm^-1 |
