Answer #1

theoretical formula for the smallest angle visible by the eye contain wavelength divided by the DIAMETER OF THE PUPIL OF EYE

Angle visible by the eye ( Angular Resolution of the eye ) is directly proportional to the Wavelength and inversly proportional to the Diamter of the Pupil

Diameter of the pupil can vary between the day time and Night .

usually, the diameter of the pupil during the day time are small because the pupil constrict in the day time .(3 to 4mm)

During the night time , the pupil dilate to transmit more light so that the diameter of the pupil increases.(5 to 9mm)

The resolution of the eye is ultimately limited by the pupil diameter. What is the smallest diameter spot the eye can produce on the retina if the pupil diameter is 3.80 mm? Assume light with a wavelength of ? = 550 nm. (Note: The distance from the pupil to the retina is 25.4 mm. In addition, the space between the pupil and the retina is filled with a fluid whose index of refraction is n = 1.336.) Hint: The size...
