Based on ability to view decreasing particle sizes, the instrument employed is: unaided eye, light microscopy, scanning electron microscopy and transmission electron microscopy.
<h3>What kind of items are the unaided eye, light microscopy, scanning electron microscopy, or transmission electron microscopy used to view?</h3>
In viewing objects, the size and nature of the object determines which instrument it is viewed with.
The unaided eye is used to view large size objects such as insects and plants
The light microscope is used to view smaller objects such as red blood cells.
Scanning electron microscopy is used view ultramicroscopic living and non-living sample such as the tissues, cells, etc.
Transmission electron microscopy is used to view even smaller objects. It has a higher resolution than scanning electron microscopy.
Therefore, based on ability to view decreasing particle sizes, the instrument employed is: unaided eye, light microscopy, scanning electron microscopy and transmission electron microscopy.
