Final answer:
The question involves the physics of lenses in a camera, focusing on calculating the minimum object distance and magnification for a given focal length.
Step-by-step explanation:
The question pertains to the concept of image formation by lenses within the study of physics, specifically related to a camera lens with a focal length of 48.0 mm. By applying the lens formula and the magnification concept, it is possible to determine the closest object that can be photographed and the magnification of this object when using a given focal length. For a lens with a focal length of 22.0 mm placed at most 33.0 mm away from the film, one would start by using the thin lens equation 1/f = 1/di + 1/do to solve for the object distance (do) to find the closest point of focus. The magnification (m) can then be calculated using m = -di / do, where di is the image distance and do is the object distance.
