Question: 
  1. Suppose for a conventional X-ray image that the X-ray beam consists of parallel rays. What would be the magnification of the image?
  2. Suppose, instead, that the X-rays come from a point source (as in Fig. 25–41) that is 15 cm in front of a human body which is 25 cm thick, and the film is pressed against the person’s back. Determine and discuss the range of magnifications that result.
