A typical bacteria cell is around 5 micrometers in diameter. The nearest we can bring our eyes to an object and still focus on it is about 25 centimeters. Using this information and the Rayleigh criterion, what size eye opening (pupil diameter) must we have in order to resolve two adjacent bacteria? Give your answer in millimeters. (use the wavelength at the midpoint of visible light, 550nm, for your calculations)

Look up the typical diameter range for the human pupil. With this information which of these can
you now say regarding your answer to the previous question:
we would need x-ray vision to resolve adjacent bacteria
our eyes are perfect size to resolve adjacent bacteria from each other
we would need smaller pupils to resolve adjacent bacteria from each other
O the last question was bogus, there's no such thing as bacteria
we would need larger pupils to resolve adjacent bacteria from each other
