- Construct Your Own Problem Consider a telescope of the type used by Galileo, having a convex objective and a concave eyepiece as illustrated in part (a) of Figure 2.40. Construct a problem in which you calculate the location and size of the image produced. Among the things to be considered are the focal lengths of the lenses and their relative placements as well as the size and location of the object. Verify that the angular magnification is greater than one. That is, the angle subtended at the eye by the image is greater than the angle subtended by the object.arrow_forwardYou hold a 5.0 cm-focal length magnifying glass as close as possible to your eye.

Determine the radius of curvature of the cornea when p = 30.0 cm and M = 0.013 0.arrow_forward
