1. The problem statement, all variables and given/known data For an eye in which the pupil has a radius of 3.0 mm, what is the smallest angular separation that can be resolved when two violet (λ = 400 nm) objects are placed side by side? 2. Relevant equations theta_r = sin(theta_r) = 1.22(wavelength/d) 3. The attempt at a solution theta_r = 1.22(400*(.000000001)) / (6*.001) = .0000813 This is incorrect. Where have I gone wrong?
