Under dark conditions, the maximum diameter of a human pupil is 7.0 mm, where an owl's pupil may be 8.5 mm. Assume a human can optically resolve two closely spaced objects at a distance r. (a) By what factor could the distance between the two objects be reduced and still have the owl optically resolve them at the same distance r? (b) If the distance between the two objects remains fixed, by what factor could r be increased and still have the owl optically resolve the two objects? In both (a) and (b), assume the wavelength of the light remains constant. (a) Number i Units (b) Number i Units
