- An amateur astronomer decides to build a telescope from two lenses. One of the lenses has a focal length of 10.0 cm, and the other has a focal length of 1.4 cm.

(c) How long will the telescope tube be if the telescope is focused on a flower that is 1.00 meter away? (Keep four significant figures for this.)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 whenp = 28.0 cm and M = 0.0140.
