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. what should be the radius of curvature of the cornea such that the image of an object 40.0 cm from the cornea’s vertex is focused on the retina?

To fit a contact lens to a patient's eye, a keratometer can be used to measure the curvature of the cornea-the front surface of the eye. this instrument places an illuminated object of known size at a known distance p from the cornea, which then reflects some light from the object, forming an image of it. the magnification m of the image is measured by using a small viewing telescope that allows a comparison of the image formed by the cornea with a second calibrated image projected into the field of view by a prism arrangement. determine the radius of curvature of the cornea when p = 35.0 cm and m = 0.0110. show all work

Anearsighted eye. a certain very nearsighted person cannot focus on anything farther than 36.0 cm from the eye. consider the simplified model of the eye. 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.a) if the radius of curvature of the cornea is 0.65 cm when the eye is focusing on an object 36.0 cm from the cornea vertex and the indexes of refraction are as described before, what is the distance from the cornea vertex to the retina? b) what does this tell you about the shape of the nearsighted eye? 1) this distance is greater than for the normal eye.2) this distance is shorter than for the normal eye.
