convex lens

-49 1 26 Experiments in Introductory Physics For Home or Lab 1. Sketch a ray diagram of a reflecting telescope with a Newtonian focus. Include the objective mirror, diagonal mirror, and eye piece. Also show the formation of the image formed by the eye piece. 2. A convex lens has a focal length of 15 cm. a) What is the radius of curvature of the lens? b) If the height of the object is 3 cm, and is located 20 cm from the lens, what is the height of the image? c) Find the position of the image as measured from the lens. d) Draw a ray diagram for the above, indicating object, image, and focal point. e) Is the image real or virtual? 3. In the problem above #2, assume the object at a distance of 10 cm in front of the lens and a) calculate the height of the image. b) calculate the distance of the image from the lens. c) draw a ray diagram of the object-image relationship. d) indicate whether the image is real or virtual. 4. An object is placed 18 cm from the screen. At what points between object and sceen may a lens of 4 cm focal length be placed to obtain an image on the screen
