A diverging lens with a focal length of -14 cm is placed 12 cm to the right of a converging lens with a focal length of 20 cm. An object is placed 35 cm to the left of the converging lens. a. Where will the final image be located?b. Where will the image be if the diverging lens is 45cm from the converging lens?c. Express your answer using two significant figures. Find the image location relative to the diverging lens.

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.)
