To review:
The principles that define an object as microscopic.
Introduction:
The size of every living and non-living thing varies at a vast level. Even human beings also vary in size from person to person. Human eyes also have a limit to view the objects that are present in the surrounding world. Human beings, as well as several other higher animals, possess eyes in order to visualize the surrounding world.
Explanation of Solution
The resolution power of the human eyes determines whether the nearby things and objects will be visible or not. The minimum distance between two objects that enables their vision as a separate object is termed as resolution. Several entities in the living world are so minute that they can be detected but cannot be resolved as separate entities. This means that such objects cannot be seen as a separate entity.
In order to view such objects separately, the eyes must equipped with an equipment that enhances the resolution power of eyes. Such objects that can be seen clearly through equipped/aided eyes only are termed as microscopic. The human eyes can view the objects that are one-tenth of a millimetre. Thus, objects lesser than the size of one-tenth of a millimetres are termed as microscopic.

Please answer questions 1 and 2 After a specimen is in focus, where in the field of view should position the specimen before increasing the magnification (be precise)? (QUESTION 2 HAS TWO PARTS TO IT): To increase the magnification, which objective should you click into position next? After refocusing the specimen with the new objective, if you want to increase the magnification even more, which objective should you now click into position?arrow_forward

- The field of view (FOV) is the entire circular image we see when looking into the eyepiece. The diameter of the FOV gets smaller as we increase magnification. It can be measured by using a stage micrometer like a ruler, measuring from edge to edge. Notice that the stage micrometer is 1000 microns (µm) in length, and the field of view under the lowest magnification is 5000 µm.
