Question
Chapter 4, Problem 1.2SC
Summary Introduction
To determine: Whether the light microscope with a total magnification of 5,000X gives a better, worse, or same resolution of a light microscope with a magnification of 1,000X and to explain the reason.
Introduction: Light has many properties, which influence the ability to view objects under a microscope and also with an unaided eye. When the light passes through a small opening like a slit or hole, the waves of light bents around the opening and this condition is termed as diffraction.

- Which of the following is true about the relationship between depth of field and magnification? There is no relationship. When magnification increases, depth of field decreases. When magnification increases, depth of field increases. Stereomicroscopes offer a lesser depth of field than compound microscopes.
