What is the diffraction-limited object size (at 25 cm) imposed by the numerical aperture of the eye (if the eye is a diffraction-limited optic)? Use 4mm for the iris diameter and 550 nm for the wavelength.
Rayleigh criterion states: for angular resolution, theta:
The Attempt at a Solution
I can solve for the angular resolution, which I got as 1.6775E-4. However, I don't know how to solve for the object size from that. Any help would be great!!
