If Sarah switched the lens from low power to high power, what would she observe?

When switching from a low power lens to a high power lens under a microscope, the individual will observe fewer cells within the field of view. This is because the higher magnification allows for a smaller area to be seen at once, thus reducing the number of cells visible in that view. However, the increase in magnification also provides greater detail of the cells that are present, allowing for a more thorough examination of their structure and features. This is particularly important in biological studies where the characteristics of cells are essential to understanding their function and anatomy. The correct observation underscores the balance in microscopy between the field of view and the level of detail, highlighting how higher magnifications can provide in-depth insights even with a reduction in the number of cells seen simultaneously.
