Final answer:
Increasing rBW will increase the spatial resolution or detail. It enhances the ability to see finer details but should not be conflated with magnification, which is the enlargement of an image.
Step-by-step explanation:
Increasing rBW, or relative bandwidth, will increase the detail or spatial resolution. When rBW is increased, the capacity to resolve fine details in an image is enhanced. This effect is similar to the relationship between numerical aperture and resolution in microscopy, where a higher numerical aperture corresponds to better resolution and thus greater detail. However, it is important to note that increased detail does not necessarily mean increased magnification. Magnification refers to how much an image is enlarged, whereas resolution refers to the ability to distinguish two separate points as distinct. Only if the image remains clear with finer details distinguished can we say the resolution or detail has increased. Magnification, on the other hand, could increase or remain the same, but if the resolution does not improve, the final image might still be blurry or less detailed.
