It allows us to know how to use a compound microscope.RESULTSThe experiment was successful because the procedures described in the manual were followed.Part 1 of the experiment, the professor he explained the details of the microscope parts and its uses very well; therefore, we were able to perform part 2 of the experiment without hesitation. In part 2 of the experiment, we placed the lowercase “e” on the stage and as we looked through the eyepiece, we saw a reversed lowercase “Ə”. In the third part of the experiment we calculated the diameter of the field and obtained a response of 10 micrometers (μm). DISCUSSION The objective lens in a compound microscope has a very short focal length compared to the eyepiece. After the light has passed through the specimen, past the objective lens, and past the focal point of the objective lens, the image formed will be reversed. This image is the object seen by the eyepiece lens. The eyepiece lens acts only as a simple magnifying glass and magnifies the image created by the objective lens. As a result, the image you see when looking through a compound microscope is reversed compared to the sample being examined. The image will be reversed due to the objective lens
