Unformatted text preview: Assignment 9, Problem 8: Some key ideas in geometric optics. The following problems should be solved graphically, by drawing ray diagrams, and not using the equations in the book. When dealing with thin lenses, remember that there are three special rays that you can draw to locate an image: (1) a ray incident parallel to the optical axis, which will pass through the focal point on the other side; (2) a ray incident on the middle of the lens, which will emerge with its direction unchanged; and (3) a ray passing through the focal point on the object side, which will emerge parallel to the optical axis. Also remember that to form a clear image, there must be a one-to-one mapping of light rays from each point in the object to each point in the image. If light rays from more than one object point land on a given point in the image, the image will be blurred. For each part, draw a ray diagram with rays from the indicated object points, and answer the questions listed. questions listed....
