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.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
