Ray Tracing and Image Formation with a Concave Lens

  1. Sep 21, 2007 #1
    1. The problem statement, all variables and given/known data

    A concave lens refracts parallel rays in such a way that they are bent away from the axis of the lens. For this reason, a concave lens is referred to as a diverging lens

    Consider the following diagrams, where F represents the focal point of a concave lens. In these diagrams, the image formed by the lens is obtained using the ray tracing technique. Which diagrams are accurate?


    2. Relevant equations

    None

    3. The attempt at a solution

    ABD, BD, AD

    I know for certain that D is true

    Then you're wrong - concave lenses produce virtual images
