The resolution of the eye is eventually limited by the pupil diameter. Find out the smallest diameter spot the eye can generate on the retina when the pupil diameter is around 4.25 mm? Suppose that light having a wavelength of 550 nm. (Note: The distance from pupil to the retina is around 25.4 mm. Moreover, the space among the pupil and the retina is filled having a fluid having index of refraction n = 1.36).
