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
