Now suppose a camera has a lens with focal length F = 65.

  1. Explain what happens to the focusing distance y as the object moves far away from the lens.
  2. Explain what happens to the focusing distance y as the object moves closer and closer to the lens.
  3. In general, why is it not possible to cross a vertical asymptote?
