What happens to the view when Sarah switches from a low-power lens to a high-power lens under the microscope?

When Sarah switches from a low-power lens to a high-power lens under the microscope, she experiences an increase in magnification that allows her to observe fewer cells but with greater detail. High-power lenses have a smaller field of view compared to low-power lenses, which means that while she might be focused on a smaller area, the cellular structures within that area are magnified and more distinct. This allows her to examine the intricate features of the cells, such as their shapes, sizes, and internal components, which are not visible under lower magnification. This transition is crucial for detailed observation in microscopic studies, especially when examining specific characteristics or differences between cell types. Thus, the increased detail observed with the high-power lens leads to a view that showcases fewer cells in a more detailed manner.
