Problem 2: a drop of water with spherical form of index n is lighted by the sun, and infinite distance object. d is the total deviation of a light ray entering the drop at incidence angle i, and get refracted after n refractions inside the drop a) find dn as a function of i, rand n. b) show that for i e |0,5|, ds passes by an extremum if n2 1. what is the nature of that extremum? if d is the extremal value of ds and i, the corresponding value for i, find c) mumerically and d for n-1 and n-2, with n-1.33. d which of the two ray n-1 and n-2 is the most deviated from the find dn normal?

People with normal vision cannot focus their eyes underwater if they aren't wearing a face mask or goggles and there is water in contact with their eyes. in a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina.with the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 2.05cm in front of the eye.)
