Question about diagram and rays

  1. Apr 6, 2013 #1
    1. The problem statement, all variables and given/known data




    Draw the ray diagrams for a pencil sitting on the principal axis behind and in front of the focal
    point of a converging lens. Describe the image. Do the same for a pencil sitting on the parallel
    axis behind and in front of the focal point of a diverging lens.

    Have you attempted to do anything? What are you asking? Just do what the problem says! Draw the picture!

    Think about what the light will do. There is not much else I can do to explain. Draw the lenses and the ray diagrams without the pencil there, then add a pencil. As for ray diagrams, google it and view some of the images that pop up.

    Better yet, just think about it first. I mean, you should get an idea of what will happen.
