Purpose: Observe a compound light microscope to learn the names of its major parts.
Research:
Microscope is an essential tool for the study of small structures such as cells. The most common type of microscope is the bright-field microscope, used for this purpose is the compound light microscope, it is called compound because it uses two sets of lenses the objective and the ocular. The ocular lens usually magnifies 10x. The objective lens can magnify 4x, 10x, 40x, or 100x.

To examine the slide of the three colored threads, and the …show more content…
Determining total magnification; first I start with the low-power objective, then the high-power objective, from 4x to 40x and I start take notes on the white sheet of paper and drawing what did determining on the low-power objective and high-power. Also,I repeat steps two to four for the color threads slid.
4. After I finished my observation I removed the slide and clean it up, turn off the microscope and wind up the wire so it resembles its original position. Place the low-power objective in place and lower the body tube. Caver the scope with the dust cover. Place the scope back in its original space in the cabinet.
Data/Result:
As a result; I observe that the field of view is largest on the lowest power objective, when I switch to a higher power the field of view closes in towards the center, and I did see more of an object to find an object on low-power. Also, on low-power it is the best to find an object just center it and then switch to the higher power.
Lab Questions:
1. What is the difference between a simple light microscope and a compound light microscope? Simple Microscope Compound Light Microscope
Simple microscope is used at s basic level, where is there is no rigorous requirement of research
Due to an added lens to a compound one, professionals use this for research …show more content…
Define resolution
Resoluion is the ability of microscope to distibguish between two points for the highest magnification, it is neccessary to use oil immersion.
4. What is the function of the diaphragm on the microscope? The diaphragm, located between the light source and the condenser, can be used to increase or decrease the intensity of the light entring the condenser and control the contrast of the
