7. [-/1 Points] DETAILS SERCP8 23.P.008. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER 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 = 34.0 cm and M = 0.0180. mm
