A Suppose For Conventional X Ray Image The X Ray

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