Question
Resolution of fossil insect eyesEstimate the angular resolution of the insects whose fossil eyes are shown in Figure $18.57(\mathrm{A})$
Step 1
Insects have compound eyes, where each ommatidium (singular of ommatidia) has its own lens. The size of these lenses is very small, which limits the resolution of the eye. Show more…

$\cdot$ You want to view an insect 2.00 $\mathrm{mm}$ in length through a magnifier. If the insect is to be at the focal point of the magnifier, what focal length will give the image of the insect an angular size of 0.025 radian?
You want to view through a magnifier an insect that is 2.00 mm long. If the insect is to be at the focal point of the magnifier, what focal length will give the image of the insect an angular size of 0.032 radian?
