Question

Appearature of human eye is 2mm. Assuming mean wavelenght to be 5000a

Answer 1

I'm sorry but your question is incomplete. But using the given information, we can find the resolution of the eye.

Hope this helps...   : )

Angular resolution limit of the eye = 1.22 λ / a

                                                         = 1.22 x 5 x 10^-7 / 2 x 10^-3 rad

                                                         = 1.22 x 5 x 10^-7 x 180 x 60 /2 x 10^-3π min

                                                         = 1 min
