Question

calculate the limiting angle of resolution for the eye, assuming a pupil diameter of 2 mm, a wavelength of 500 nm in air, and an index of refraction for the eye equal to 1.33. calculate the minimum separation d between two points that the eye can distinguish, if the points are at a distance L = 25 cm from the observer. If the eye is dilated to a diameter of 5 mm, what is the minimum distance between two point sources that the eye can distinguish at a distance of 40 cm from the eye?

Answer 1

Combining EQ1, EQ2 and EQ3, we get,

........EQ4

Part 1:

using EQ4, we get

Part 2:

using EQ4, we get
