The focal length of a simple convex lens used as a magnifier is 10 cm. For the image to be formed at a distance of distinct vision D = 25 cm, the object must be placed away from the lens nearly at a distance of

The figure shows a simple arrangement which works as an astronomical telescope. The arrangement consists of two convex lenses placed coaxially. The lens which faces a distant object is called the objective. It has a large aperture and a large focal length also. The second lens is closed to the observers eyes. It is called the eyepiece. It has a smaller aperture as compared to the objective. Its focal length is also small in comparison to objective. The objective forms a real image of a distant object. This image acts as the object for the eyepiece. The eye-piece may form its image at a large distance (oo) or at least distance of distinct vision (D = 25 cm). The magnifying power of the telescope is the ratio (-beta)/(alpha) . Maximum angular magnification is produced when the final image is at the least distance of distinct vision.
