A lens with two convex surfaces, both with radii of curvature of
0.25 meters, is used to focus light. If the lens is made of crown
glass, it would have an index of refraction for red (656 nm) light
of 1.509 and for blue light (486 nm) of 1.517. What happens when it
is used to make an image of a distant source of white light? Pick
those that apply.
A. The red light focuses closer to the lens than the blue
light.
B. When the red light is in focus it is surrounded by a blue
halo.
C. The blue light focuses closer to the lens than the red
light.
D. The red light falls in a cone outside the blue light as it
the light converges to a focus, so when blue is in focus there is a
fuzzy red ring around it.
