Why might an examiner choose a microscope with a lesser magnification to study a specimen?
What will be an ideal response?
As magnifying power increases, the microscope’s field of view—the size of the specimen it can study—decreases. The microscope’s depth of focus—the thickness of the specimen it can study—also decreases with increasing magnification. An examiner might first select a lower- magnification microscope to get a good general overall view of the specimen, then switch later to a higher-power microscope to study smaller portions of the specimen in more detail.
