Final answer:
The statement is true; lower magnification leads to a larger field of view and depth of focus, which may allow for the observation of both direct and indirect retro illumination at the same time.
Step-by-step explanation:
When magnification is low, there is indeed a larger field of view and depth of focus, which can allow for the simultaneous observation of direct and indirect retro illumination. Therefore, the statement given is true.
Lower magnification results in a smaller image compared to the object, and this is typically true, be it in the context of a concave lens used to correct myopia (near-sightedness) or the use of a microscope or telescope. With the larger field of view, more of the surrounding area can be observed, and a greater depth of focus allows for more of the image to remain in focus at one time.
