Light of wavelength 500 nm, near the center of the visible spectrum, enters a human eye. Although pupil diameter varies from person to person, let's assume a daytime diameter of 2mm.
Estimate the angular resolution for this eye, assuming its resolution is limited only by the diffraction.
PS: what's the bright fringes m in this question? How to determine it?

Θ = 1.22 λ/D
= (1.22 . 500 x 10^-6)/2
= 0.0003 rad
