Light
from a distant star is focused by the lens onto the retina (Intro 1
figure) . With a pupil diameter of 3.0 mm, the intensity of light
falling on the retina is illustrated by the graph below (Intro 2
figure) . The spot illuminated on the retina is about 8 μm in
diameter.
When star gazing on a very dark
evening, the pupil diameter will expand to much larger than 3.0
.

SOLUTION SET UP The center of curvature of the first surface of the lens is on the outgoing side, so R = +6.0 mm. The center of curvature for the second surface is not on the outgoing side, so R2-_5.5 mn. We solve for f and then use the result in the thin-lens equation. Now we'll apply the thin-lens equation to the eye When light enters your eye, most of the focusing happens at the interface between the air and...
