The resolution of the eye is eventually limited by the pupil diameter. Determine the smallest diameter spot the eye can generate on the retina when the pupil diameter is 2.78 mm? Suppose light with the wavelength of 550 nm. (Note: The distance from the pupil to the retina is 25.4 mm. In addition, the space among the pupil and the retina is filled with a fluid having index of refraction is n = 1.336.)
