Chapter 2, Problem 5E.1RQ

Summary Introduction

To explain: The reason why the body tube of the microscope should not be lowered while looking through the ocular lens.

Introduction: Microscope is an optical instrument that is used in visualizing objects that are too small to be seen with the naked eye. Minerals, microbes, plant cell, animal cell, and many more can be magnified and viewed with a microscope.

Explanation of Solution

The body tube is present just above the stage of the microscope and attached to its arm. It houses the objective lens and eyepiece lenses that magnify the specimen. The body tube can be lowered or raised with the help of coarse-adjustment as well as fine-adjustment knobs. These knobs are located above or below the microscope’s stage. The body tube must not be lowered while looking through the ocular lens because it might cause the slide to break.
